content: Hello Folks,Made a rather nice run on a huge auction the other day, the plan is as I have done twice before: sell the stuff and keep some of it with the profit, so...*EDIT (corresponds to V1.0)* The below stuff is Pt.1 I'm roughly halfway through the list, more to follow.*EDIT (corresponds to V1.1)* Added all other stuff except for LA modules. Stricken TDS754D (SOLD).*EDIT (V1.2)* LeCroy DA1855A sold, added some pics & datasheets*EDIT (V1.3)* HP8664A added*EDIT (V1.4)* Some units sold, checked.. Removed stock pics.*EDIT (1.5)* Modified the table to reflect some newly checked units, cleaned up first post a bit.*EDIT (V1.6)* Added the LC574 #. Modified the 9210 pulse gen post. Added a price for the TDS6604 and updated that post.*EDIT: I'm not maintaing this post anymore, but I updated the sold list so people don't get confused- All units in, not all of them checked.- Units listed are sold to me as operational, but I'm still checking them. If you're interested in a non-checked unit it will be checked before any payment is required.- I bought a number of other units with question marks. None of these will be offered before I can check it out for myself.- Before anything gets shipped out I will do whatever diagnostic the device features plus asimplefunctional test. Ie: put a square wave on all channels, see if it shows up.Not"Hey, the slew rate here is 625ps and it is listed as 583ps, let's take it apart".- Non-conformities beyond what such a functional test would show are beyond my responsability. Should there rise issues with the interpretation of this, I'll raise the question here to see what the consensus on the forum is.- You can ask to do additional testing at no cost within reason and the capabilities of my gear.- If you are interested in one or more unit, let me know in the thread or per P/M. Please don't use the thread to haggle though.- No probes or accesoires included unless otherwise stated.- You will see a "VAT" and "Without VAT" price.-> If you are a bussiness inside the EU with a valid VAT registration number, the no-VAT price applies-> If you are a natural person inside the EU, you'll have to pay VAT. As the unit will be shipped from Belgium, there will benoimport charges, duties, whatever.-> If you are outside the EU, the no-VAT price is applied but keep in mind you may be carged import duties/fees. These are all for you, not my responsability- I may refuse shipping to certain locations- The listed price includes Paypal charges. If you pay through a regular bank transfer you can substract that amount from the price but the option "originator pays fees" or something like it must be selected. Ie, if you pay 1k€ I must see 1k€ pop up on my account.- Shipping adds to the price.- These prices apply to members of EEVBlog in good standing. I set the prices to be lower than eBay prices because I assume decent members here have a good understanding and some trust already exists. I will not sell to one-time posters under the same conditions.- ALL PRICES IN €

content: Firstly, forgot to say: obviously if a unit is reserved but it turns out it's in bad shape or there are issues the advance will be returned.WhyIdo it has two reasones. 1) This is putting a huge strain on my budget. The auction went a bit better than I thought, so I need to find a way to get some money back in. 2) I'm contacting some second hand T&M dealers right now (they don't seem to mind working with prelim info) but would still prefer to sell this stuff here. As those folks might take a whole wad out of the inventory I'm giving the opportunity to sign in now.Whyyouor anyone else might want to do this is also easy: get in first. You help out by aleviating my little cash flow issue, you get first choice.Or you can just wait untill it all arrives and decent pictures are availble. It's just another choice you have.

content: Thinking about a way to test these units. I guess the Lecroy 9210 pulse gen would come in handy to check the scopes... verifying the slope on all channels. Would also bypass me not having +500MHz active probes, BNC would work just fine.Any suggestions for the others stuff? What would be an interesting/representative thing to measure with the SIA-3000 units?

content: Also thinking about offering the option to include 500MHz passive probes for those scopes. I could buy a bunch in bulk and offer them at cost to make the package more complete. Would that make sense? Looking at some German probes:http://www.farnell.com/datasheets/43854.pdf?_ga=1.31028026.469541086.1414004735Would be able to offer them at 100€ (ex taxes) a pop if people are interested. Thoughts? Suggestions? I'd be interested to hear opinions, not just if you have any intention to buy one of the units..

content: Holy F**K!!!I chartered a local shipping company to pick up my stuff, package it and ship it. That was 6.whole.weeks.ago.Today I received an update: stuff is ready to be shipped and will do so... in another two weeks. The ship itself is actually still in Rotterdam atm (Maersk Missouri, if anyone cares). The bloke mentioned it might actually advance a week (this would be the first time they advanceanything). Regardless, it will be mid-oktober before I get my mitts on the stuff.And to think I originally assumed to have it before September.Now, if you'll excuse me, I'll go work some more to keep the bills payed untill the goodies get here

content: Finally got my gear:Been wrapping my head around the question on how to "present" al of it around here. Some stuff will just require power-on, quick verification and hopefully a sale, other stuff will probably need some work and effort. Rather than to spam the forum with a gazillion threads for each of the units, I figured I'd just contain it here. A single post in this thread per unit. As some of these posts will be repair rather than sell related, I suppose that strictly speaking it will be posted in the wrong place. As far as I can see, this is the lesser of two evils but it the mods don't agree: let me know!

content: HP 8664A #1I got two of these, both were sold as not powering up. Starting out with them as I am hoping to use them as a verification source for other gear (and because I want to know if the gamble worked out). I didn't pay much for them but...The two person lift warning is not a joke. You could moore the QEII with this thing. That also means that, while they didn't cost much, the shipping was an absolute killer.Front is in pretty good shape. This may be my favorite part:Yes, this is an old machine, but it has been used and maintained untill fairly recent... After a quick check of the fuse (OK) and a check if there's a 110/230 switch (no, universal) I figured I might as well give it a go...For a unit that doesn't work, this isn't half bad! Nice and bright VFD's as well. And the, uhm, arbitrary code generator seems to work nicecly as well.. No for the not-so-great news..Doesn't keep it from working seemingly well. Will have to get the manual for this stuff, I guess. No N-coax here atm (probably Tuesday) so I can only check the audio output (which works well, aparently):So, will have to dig in the maintenance manual if I can find it and I'll have another go at it when I have a suitable coax adapter. All in all, beats a dead unit by a mile!For Sale?No, too many errors and if it works I'll be using it to check the scopes...

content: LeCroy DA1855A PR2It was listed in the price list before, but this was one of the few things that sold "on faith" (and by averypatient buyer). If you look closely, you will see it was listed as a "regular" DA1855 in the list, which was an oversight on my part. The price was set accordingly. I'm not going to backtrack on the sale, so if the unit is good, this should be a very happy buyer (who thusly gets rewarded for his patience!). But, verification first.DatasheetBoth channels include a precision voltage reference that can be used as one of the inputs. Easy to check:Close enough!The top plate at the back is a bit banged up. Nothing life threatning, though. Had a peak inside, there'snothingthere untill roughly halfway the case.That is, unfortunately, as far as I got. Tried to get any kind of trace on the scope, using an input from either the probe comp pins on the scope or the audio output from the HP sig gen. Didn't get anything. My guess: I'm stupid and I don't understand how it works. To be continued.EDIT: Work continues. Can't get any signal out of the unit except for the reference voltage). Getting rid off the top plate reveals two "standard" DA1855A's, excellent craftmanship and alotof free space.Taking off the top (and a lot of other screws that weren't required)... A huge thermal pad (Bergquist by the looks of it) that's kept in place by spacers in the top cover), an RF can (which is closed by the top cover, I would have guessed this would still allow for a substantial gap but the top cover shows where the can made contact so I suppose it's good enough) and some botch work (flying components, 1206 components with two more added in a "tent" configuration),...So, how to get this started? Well, let's start with the beginning: check where the signal comes in and take it from there! So channel one.. Bingo!The second schannel is OK, though. So, chances are this is not the "final" solution. One of the reasons I got this heap of gear is not just to make a buck, but also to learn a thing or two. As is the case here. I need to rethink a bit what I know or think I know about differential signals. These coaxes seem to come in without the shield connected at all. Somehow, this does not connect with how a had things in my mind. Which may also be the reason why I never got anything out of Channel 2. Need to think about this a bit.EDIT: Revisited Channel 2 with a better understanding of the whole thing: got it to work now. Then repaired the coax on Channel 1 (including the shield conection that broke off as well..) and... Still no dice!! So I figured I'd check out other coax connections and sure enough! Another one broke loose. Pictures I took are not good enough but after a quick fix Channel 1 is good to go!Ready to Ship?Yes! I'm guessing that despite the delay WVL_KsZeN won't be unhappy: he's getting a 2-channel unit where he (and I) expected and payed for a one-channel device

content: TEK TDS754D 500MHz 4ChSupposed to work fine. Boots up nicely, but... Probe call output gives this (when tapping on the channel button, otherwise it stays flat). It is like this for all channels, for the internal probe call and an external one.https://goo.gl/photos/3esB78Vp3SLLgDNZ7Hmm, I'm thinking this one may need cracking open.. No time for that now, though...

content: HP 8664A #2Well, this seems to be the first truly nice surprise. This one was not supposed to be not working either but boots up like a charm. Nice bright VFD's. Just like the other one relatively recent calibration stickers. No dust buildup visible on the fans or anything. Unlike the other one: no message after boot. Ran the built in test just to be sure and:Clean sheet! A few dents on top, I pressume from another piece of equipment that sat on top.Back:Note: unlike I mentioned in the other post, thereisa 110/230V "switch" of sorts. The fuse assembly includes a kind of configuration card you can put in in two orientations thus selecting the voltage. I was just lucky.EDIT: OK, got my N-Type-BNC pieces and hooked up the generator to the Yokogawa 1.5GHz scope (which is another story). Seems to work fine:For Sale?Yes, as this is a big hunkin' piece of metal, I'm not adding shipping quotes. Carrier and cost will depend on location.

content: LeCroy 9210 Pulse Gen with 9211 moduleThis unit was supposed to help me check out scopes and other gear, firing up a pulse with a known edge and see how it goes.See the problem? No? Let me help, with a picture from the auction:The frontplate from the module is gone. At first I figured this wouldn't help with the resale vale but "oh well, I can still use it for testing". Turns out I can't. There's a "disable" button on the front plate.A picture from the back and a piece drifting around in the packaging material. No, the frontplate wasn't there. No idea where it could have ended up...A shame, really, because the self test is fine:EDIT: For the lovers of fine vintage electronics:All TH? Not quite... Also: look at that big honkin' LeCroy IC!For Sale:Sure, but I don't think there are any takers ;-)What Now:This one is going back to storage. Don't have time to do extensive teardown & repairs, that will be for H1'17. The front connector seems easy to reverse engineer. Maybe make a little breadboard with a connector and a few buttons. Maybe 3D print a front plate. Should be fun, but not now...EDIT: Yay! The front plate turned up. Was wrapped in with another scope. Still loose, it doesn't snap into place but that's easy enough to fix. Works fine:Checked it in the post with the second LeCroy LC574.For Sale:Mhh.. Sure, but I'm not sure it's worth the bother. Probably not worth all that much, but it's still a nice tool to have around. Think I'm gonna hang on to it for my own lab. If you're interested despite this, let me know.

Just a thought..What now? Thing has a VGA output, so the plan is to crack her open, disconnect the display assembly, see if she boots again and attach an external screen.

content: LeCroy LT344 4Channel 500MHz 500MSa/sUnit is in pretty good condition and it was calibrated two years ago.. Always like these hardcover screen protectors.Unfortunately, that apparently didn't keep one of the knobs (zoom) to go missing. Only blemish on the otherwise damn good shape this unit is in... Had a LC584 before and the interface feels very familiar. The display is still plenty bright but the viewing angles are about what you can expect from an old LCD display (pretty shitty). But... What's up with the 500MSa for a 500MHz? Must have missed this class in school.. Anyway, this is what that looks like on 100MHz:Count'm: yeah, 1,2,3,4,5 per period. Well, at least it's clear what it is doing... Works fine on all channels. On 10MHz:For Sale?Yes!Sold.ReturnedSo, this one came back. The trigger circuit seems utterly fried. Doesn't take a trigger from any channel, or the external channel. The service manual is quite extensive, and because everything else is working I assume a trigger-only chip has lost it. Like the MST412. Can't even find it on the board though... Nothing else seems fried. Don't have the time for it, if anyone has a clue, let me know!

The display is a leftover from hacking an 800x600 screen into a TLA704 which I have sold a while ago. Which TLA modules do you have? If I where you I'd check Ebay selling prices first because most of the TLA modules are not worth much and you may waste your time & effort.

content: LeCroy LC574AL 4 Channels 4GSa/S 8Mpt #1(On 1 channel, divide by 4 for 4 channel mode)Unit is in pretty good shape, aside from some scratches etc you may expect after 10+ years of use. Backside:One thing I must mention: this thing isloud. I meanLOUD. Not the kind of loud that the bearings of the fan may still be in Kansas (seems to run absolutely fine) but the kind that makes you think they sure didn't want to have cooling issues. Or perhaps the engineers used it to blow dry their hair. Aside from that: even though I never heard of LeCroy before last year, their stuff is growing on me. Yes, the interface is a bit quirky but once you get the hang of it it allows for some speedy wizardry. And from my experience, they seem to have been build to last. Little to no trouble with it (if you don't count the mysteriously missing frontplate on the pulse gen or the diff amp that I either don't get or is broken). Firing on all four channels (with an external 5MHz source (I think) and the internal gen to 2MHz:One of the first things you'd think would break, but no. Not sure if this would see much use but hey:On a single channel, with multi cycle feature enabled, 250MHz:Note the parameters: 4ns average. Spot on.Vertical accuracy, with a Rigol DS3058 as source, set to 1V. Sorry that the DMM isn't clear, it indicated 1,0007VScope has 1,002V. Pretty decent!

content: Tek TDS820 2 Channel 6GHzYeah, that's 6GHz. Kinda missed one of the coolest features, though: 14-bit vertical resolution. Beats the usual 8-bit like... well, something really cool.My affairs with Tek stuff have been less than perfect, so the thing even booting up was a pleasant surprise on its own.The unit actually starting the diag cycle was another one. Finishing it left me euphoric (that was a first for me!). Unfortunately, that euphoria faded fairly fast:Ch.1 Sampler - FAIL.F.U.C.K.On the bright side: one functional 14-bit 6GHz channel.What's next:Getting SMA adapters to get both channels tested (hey, not gonna start believing anything Tek says). If Ch1 is dead I'll probably set it aside untill I have more time. Unless there's someone with a direct interest, in which case I'll happily bump it on the list of stuff to crack openEDIT: SMA adapters in. Channel two checks out:But once the generator hits 1.5GHz, it turns to shit. Not sure who craps out, the gen or the scope but, well, that's it.Channel one is a no-go. The odd thing there is that the trace is stuck at a certain position: doesn't matter if you change the vertical position, the horizontal trace representing Channel one remains where it was.What's next:If anyone is interested, I'll crack it open, check it out and probably recap the acq board. If not, back to storage untill I have time to spare.

Not sure what I'd do after because I don't really know what this thing is supposed to do, so I won't be doing any measurements beyond the built in testing.And right now, not even that.Right of the bat, it has 6 (six!) voltage selections.I mean,why? What can't you do with a 110/220 switch that you can with a six-way switch??Anyway, no direct luck after setting it right. Fuse, then:That's cooked alright...

One right after the other. German Engineering folks! Unfortunately, non-functional engineering. The on/off switch feels a bit odd though (some overly complex cat-eye thing). So: off comes the lid!MyGod! This is one tidy unit! Not a wire out of place, color coded circuit boards. And as complex as it seems, it still feels like I could take it apart in two minutes if I knew what I was doing.. And these boards? All chock fullUnfortunately, wrong side of the box for the power switch. Not to worry, though, the bottom comes of just as easy.More tidiness and also the reason why the power switch felt "odd". That long metal rod goes between the button on the outside and the actual switch. I mean, theremustbe an easier way to do that? That assembly must have cost about as much as a modern day chinese DMM or something!Doesn't seem to be an imediate problem though, next step: try to figure out how the switch works electrically. But that for tomorrow. I hope.EDIT: switch is fine, unit doesn't do anything at all. As someone already mentioned: not the most valuable piece of equipment, so I put it back together and it's going back to storage for the time being.

content: That Wandel & Goltermann PCM-4 would have been very useful to me 15 to 20 years ago when I was involved in designing digital telephony systems. It does bring back memories of fun projects I worked on though so I had a nice blast-to-the-past by going through the specs. Nowadays it is rather obsolete because (almost) all these lines have been replaced by fiber optic links with VOIP. But maybe yours has a rare option which is useful to somebody.

content: LeCroy SDA 100G XXL MainframeScope LeafletThe good news: the 100G stands for 100 GHZ. And no, that is not a typo.The bad news: this is the mainframe only. Even though I obviously hoped there would be a doggy bag containing 4 pristine modules for it, no such luck. Wasn't counting on it, though, so no need to worry about my mental health.Minor bummer: the one of the feet is missing. Not exactly a deal breaker, but still: this sucks for a unit that is otherwise in pretty decent shape.. The screen is actually pretty nice (large and acceptable viewing angles).The bootup is horrible though (Win XP). Takes about forever. Once everything runs, the interface is smooth and, well, modern. Feels pretty good, intuitive. Boatload of options (browse around the leaflet for a feel of it).Note: I know the pictures suck, I'll retake them tomorrow.Installed options:- XXL -> this means 512Mpt. Again, this is not a typo. It's MEGA!- Software option: XDEV/MATH, the standard advanced math package (I think).I wanted to see if there was any kind of self test sequence, but I think it's hidden behind the service button (and that one has a code). So, if anyone knows the code they ussualy use, shoot me a PM.Basically, this unit accepts up to 4 modules, electrical 20,30,50,70 or 100GHz (the 20 apparently doubles as a TDR!) or optical 10, 25 or 50GHz. They can actually be had for about 3k€ directly from LeCroy for the 30GHz version! I'm going to try to get 10k€ for the mainframe (including VAT and eBay fee) so you would pay 13k€ for a 30GHz 1Ch scope with a 512M record lenght. 16k for 2Ch and so on. Not exactly expecting to sell it overnight, let's just see how this goes...Needless to say I would beveryinterested if anyone had access to one or more modules for a reasonable price...For Sale?Yes!

content: Quote from: Ice-Tea on November 08, 2016, 09:04:07 pmNo, but it's a sampling scope, not a real-time scope. The sample rate is actually just 10MSa/s using Coherent Interleaved Sampling.It's a great scope if you work with modern high-speed serial communication systems but it's essentially a very niche scope. A bit like the Keysight DCA but more powerful.

content: Wavecrest SIA-3600DProductlineLeafletManualPleasant surprise: was supposed to be a 3000, it is a 3600D. Was also supposed to be a 2-channel unit, it has three. Which is odd, it is supposed to have 2,4 or 5. Not complaining, thoughAlso has pattern marker enabled on Channel 1. Whatever that means.Want some more odd?The unit is labeled "6GHz BW Osciloscope". Sampling, off course. Now, here's the leaflet excerpt:Not that 6GHz is bad in any way, but... Odd.Want some more odd?When you connect the power chord, the power supply and fan turns on. I figured I was screwed, power supply on the way out, unit about to burst in flames and such.. Not so much, though:This isby design.All channels work, this thing is chock-full of stuff. Some examples below. All three channels work, channel three is pictured. First up: built in 10MHz reference1Ghz from the HP gen:3Ghz from HP gen (also verifying the gen)Cosmetic shape is OK, but some scratches.For sale? Come and get it! I have a few of these, but I think the others are "plain" SIA-3000's

content: Tektronix TDS684B 4Channel Color 1GHz 5GSa/s Scope #1In all honnesty, the heap of Tek scopes have been less than kind to me. Most have one issue or another that has send them to the long list of "I'll get to it when I have time". This one is not perfect but still not bad. The display is quite good (some of these are quite dim). The case itself has some gratings (check above the Tek logo, the left bottom side,...) and some idiot decided that encasing a sticker in resin on the front was a good idea. That isnevercoming of. The probe compensation pin lost its, well, pin (but still works) and the clear screen button gets stuck easily.Like quite a few of these I've seen pasing by, starting the diagnosis cycle results in the unit crashing and rebooting. Other than that, the unit seems fine. All 4 channels check out, both on the probe comp pin (with a 500MHz Agilent passive probe) or on the external generator (1GHz terminated on the scope in 50).So, for sale?Within the limits above: yes. If you'll ask me nicely, I'll probably shave something off the price for the mentioned limitations.

content: Tektronix TDS6604 4 Channel Color 6GHz 20GSa/sScope DatasheetNote: could't find the "regular" 6000 datasheet. Should be more or less the same except for the computer part of it, but be advised...4-Channels, color, 20GSa/s, real-time scope. Huzzah! Let's see. Backside first.What you would expect: GPIB, VGA out, CD drive, HD access panel. The OS stickers says 98SE. There appear to be some options installed: SM, ST, JT3, RTE. The actual key was printed on a sticker, I've taken the liberty to black it outFrontside looks pretty OK, some sticker residu. I'll get rid of that later. Topside plastic has faded a bit. Intensity knob is missing though...Windows 98SE? Not so much. It has been taken care of and calibrated in the past so I don't really get why the OS sticker was not on the back. Oh, well.Now, the frontpanel also revealed one of the challenges of this unit: it has a proprietary probe interface. Bummer? Well, yes and no. You can't do anything without adapters etc but on the bright side: probes for this unit will not be sold that easily on the marker due to their proprietary nature. And it seems this has made the prices more or less reasonable. So, I got me a 6GHz active probe.All sorts of accesoires/heads, cool stuff. I don't exactly have something with a nice and high speed signal to measure laying around, so once more turning to the HP signal gen with a hack solution (coax with two crocodiles connected to TH resistor ends stuffed in the holes in the probe... yeah, I know...)Now for the bad news.CH1 seems utterly cooked. Whatever you do with it, it turns it off due to an overload. As for the other channels:Bit noisy. My guess is the setup doesn't exactly do it justice. I have a TCA-SMA and TCA-BNC inbound, should get me better results. So, what about measurements? Set the generator to 10MHz, 250mV (peak).Because of the noise, the frequency number jumped around a bit but in general: spot on. As for the amplitude: seems off by a factor of two, but it is not. The 250mV actually assumes that the source turns out 500mV with 250mV dropping over the generators series resistor and the other 250mV over the load termination. Without that 50termination, the 500mV ends up on the high impedance (ie 10k) load. So: pretty good.Passes self test OK (forgot to take a picture). Options installed: Jitter Analysis, Serial Mask Testing, Serial Pattern TriggerAlso: one of the fans is getting ready for retirement. Sounds like a coffee grinder (a small one). If anyone is interested in this unit I'll get to it before finalising the deal but otherwise I'm setting it aside for a later time. As for the toasted Channel1: not going to touch it now, maybe never. Rather have a great 3 channel unit then taking the chance of toasting them all.As for the near future: I'll give the SMA and BNC a spin, maybe do a call run with them and, well, that's it.So,for sale?: Yep. I still need to update the excel on the first post, I imagine it won't quite catch the same price with only three channels. Probably will just do 3/4 or so.EDIT: Can't do any calibration on the unit because it craps out with the cooked channel 1. I'm offering it at half the price it was listed it for before. Might decide to crack it open somwhere down the line if it doesn't sell.

content: LeCroy LC574AL 4 Channels 4GSa/S 8Mpt #2(On 1 channel, divide by 4 for 4 channel mode)EDIT: that's actually not true. Wuerscht informed me you need some special Lecroy Gizmo to combine two 2GS/s channels in a single 4GS/s. Wonky marketing, that.Unit is in pretty good shape, aside from some scratches etc you may expect after 10+ years of use. Knobs seem a bit more "grainy" and wobbly than the other unit. All seems to work, though... Last calibrated in 2014. Fun surprise: the missing frontcover from the LeCroy 9210 pulse gen module that was missing (see post on the first page) was wrapped in together with this unit. So, let's put it to good use and get both of the verified! Pics are a bit grainy but should do fineChannel one and two, no complaints.Three and four, perfectly fine.Now, let's play around a bit. Zoomed in, single shot:You can see the actual samples in this shot (1GS/s) Corresponds to the 1ns trs set on the pulse gen. Enabling RIS (repetitive signals only) which gives 10GS/s equivalent sampling, clear difference. Might be a gimmick, but it still showcases the quality of the front end.The unit should be able to do 4GS/s on a single channel. So, there's a "Channel Use" setting that can be set on 2 instead of 4. Which gives 2GS/s.Yay! No... Wait, 2? Supposed to be 4GS/s? Where's the "Channel Use = '1' => 4GS/s" option? Odd... Anyways, yet another lovely LeCroy. Liking LeCroy gear more and more. It just... Works. And once you get the hang of it, they are pretty nice to use!Also: hurrah for the 9210 pulse gen. Seems in good shape. The front cover is still loose but that's nothing a bit of decent glue won't solve.For Sale?Well,... No. Remember how I said LeCroy gear "just works"? Remeber the LT344 I sold before? It might be coming back. Apparently, the trigger doesn't work as it should. I might be able to fix it, or the customer might want to get a refund. But he actually expressed an interest in a trade (up) and that would be this unit. So gonna set it aside to be able to keep him a happy trooper.The trigger from the LT344 is cooked but the customer asked for a refund. Which he got. So, this one is for sale!

content: LeCroy SDA6020 4Channel 6GHz 20GS/s, 32mpt; 10 000 segmentYou won't find this one listed before because it didn't boot. After quite a bit of XP nudging and tweaking I got this far (see picture).Unit seems in good shape functionaly but is still in need of more testing and some TLC (cracked front bezel I need to sort, BNC at the back is bent, some PSU whine etc etc) but it seems like this one will make a full recovery. And be awesome once more! Stay tuned for this story
