content: I will collect all the other issues I come across in this thread. Stay tuned ;-)The record length of this scope is just 10k and it is fixed. Therefore when going to a large timebase the sample rate naturally goes down. To be expected. Unfortunately this also severely hinders triggering on short spikes, as they are likely to be missed - even in edge trigger mode + peak detect. Now I would have thought that for more fancy trigger options that is unavoidable (like pulse-length trigger), but at least for pure edge-trigger it should be possible to sample with a higher rate until a trigger event is detected and then switch down to whatever is dialed in... oh well.This time it is a displaying issue when switching between trigger options (auto/normal/single) and involves reference traces, window zoom and some funky "special effects" (unwanted of course).* The "reference trace" (stored data) is only displayed when the "live trace" has seen a trigger event ! ? ! (madness)* The "reference trace" vanishes when switching trigger modes* Window-zoom is only available in "normal-trigger" (only triggered once) when the run/stop button has been pushed* Sometimes the trace vanishes* In "normal trigger" the trace is severely distorted / misplaced when moving it on the screen* In "single trigger" it is OK.Probably more to come soon...

content: As the sample-rate goes down at large time-base settings and the record-length is fixed (10k), the screen refresh rate goes down dramatically.Unfortunately the whole scope seems to become sluggish. Everything seems to wait for the ongoing sweep to complete. This is a bit subjective I must admit. I had the impression that the only way to reset an ongoing sweep is to change the timebase back and forth. I will have to re-check that.My old analog Tektronix 314 can easily be set to store a new image every X seconds. And of course you can reset the cycle and rearm it anytime. And it doesn't miss a trigger due to low sample rate either.Don't throw away your old analog scopes!

BUT the insulation of the cable (always too short) didn't play nicely at all. I did a few tests and it starts to disintegrate at about 120°C - ARGH

content: Simple answer: to get what I payed for!If they choose to re-brand other products - fine. Still I can expect them to subject these products to the usual testing and quality control procedures. If they don't... well we all know what should happen to a company that doesn't do adequate testing.I don't know yet what my support request will lead to, but I currently don't think I will EVER buy a Le-crook scope again - be it as a private person or on the job.If I had enough money to spare I'd get me a nice chainsaw and cut this rotten thing in half and send them the pieces for "further inspection".

If you wish support you will have to pay more.

content: Quote from: madworm on May 11, 2012, 07:01:19 pmYou can expect that, but nobody in the business does it. When you buy a cheap import with a name brand, what you get for your money is a better chance of having an english speaking contact for warranty repair and not much else. You can't count on better design, reliability, or testing than if you bought it from the OEM. You might get friendlier service, but it won't be much better as the reseller typically won't have spare parts, diagnostics, or technical expertise related to the product and will have to forward all but the simplest requests to the OEM.Basically you shouldn't pay a premium for a rebadged device. They perhaps made sense when it was more difficult to buy the chinese stuff directly, but now if you want to buy a cheap Chinese import, buy the original. At least buy from a lower tier rebagder that doesn't charge a huge premium. You will get a cheap product at a cheap price. If you want to pay more and get a name brand, find a manufacturer that still designs their low-end products in house.

content: Well I didn't buy it just recently. I got it two years ago but didn't have access to it (don't ask). And it was a promotional offer (about 20% cheaper), so it seemed like a good deal at that time. Initially I wanted to get the top-end Rigol, but the seller (US) refused to export to the EU - told me he was 'asked' by them not to ship it. The EU prices were considerably higher... the usual rip-off.Again, if Lecroy don't fix this they can go to HELL as far as I'm concerned. I don't know if the low-end scopes of their competitors are any better (I do hope so), but you just don't do business like that. If a company chooses to misbehave like that, they surely won't see any business from me again. Ever. And if they desire my eternal wrath and seek a shitstorm, well... they can have it. Not that they will give a damn about it, but they can still have it.Low-end devices naturally have 'weaker' specs, less bandwidth, less features, may be slower and so forth. That is to be expected and fully accepted. Cheap CPUs for example are slower - well known fact. Cheap digital cameras don't record HD videos, don't have image stabilizers, but still take decent images.What is not to be expected are FRIGGIN' BUGS! Apparently unfixed for at least 2 years as it seems. They should change their name to bloody Microsoft.../rant

content: Its a reason eevblog is so valuable, before it we rarely heard of problems with MTE gear, much less teardowns. Most electronics forums on the net are useless, helping students with homework or newbies how to do ohms law. Professional forums are so water downed, its nearly useless. The newsgroups were helpful, if you can stand being insulted or the SN ratio.Kudos to madworm to bringing this up; IIRC there is a Lecroy rep in the forum, maybe they can do something about this now that its public. I recall Fluke moved on a unknown bug in the long discontinued 85 III DMM, and gave the owner a new Fluke 87V in exchange after he found and complained of it; I have one of the 85 III and confirmed the bug, it never goes into sleep mode.

content: I have no experience of LeCroy but was looking at the Wavejet as it is heavily discounted at present.From what people are posting here, perhaps I should avoid LeCroy altogether? Is the Wavejet a proper LeCroy scope or is it a higher grade Atten?Choosing a 100MHz scope is difficult at present. Tektronix have very low specs for the money. Rigol have the tempting DS2000 series but are a bit of an unknown. Agilent are rather pricey and have left off an annoying number of features on their 2000 series (only 100k memory, no hardware frequency counter, no arbitrary wave form or modulation on the function generator and a number of other things) and it would appear that LeCroy is not a brilliant choice!

I'm looking at buying another 9354AL, fully loaded (~$1700) on ebay, there's plenty there. Don't know whathappened since they went to LCD screens, but not looking good. Sad.QuoteBeen looking for a portable CRO for a few weeks now, and it's NOT getting any easier to decide. What a mess. Currently, I'm stuckon the GW Instek (at ~$1,800). Oddly, It seems that there are NO sellers(?) that will offer ANY discount ! Seems odd to me.

content: Quote from: jpb on June 15, 2012, 09:23:14 pmLeCroy developed the first DSO and they are still one of the top vendors for DSOs in the higher price range. Then again, their entry products are unfortunately rebranded overprized China crap nowadays.The WaveJets are somewhere in the middle. The WaveJet line was aquired by LeCroy from a Japanese Vendor called Iwatsu that had a reseller/manufacturer relationsship with LeCroy before that point. So WaveJets are not genuine LeCroys in a way, but they are also definitely not rebranded China crap as the WaveAce or WaveStation entry level stuff.Quote from: jpb on June 15, 2012, 09:23:14 pmAs pointed out in the other thread: you should have a loot at the Hameg HMO scopes. They are pretty good value for the money and Hameg has good customer support compared to Rigol and the likes.Quote from: digsys on June 16, 2012, 12:40:38 amWe have some of these old school orange CRT LeCroys at work, but in no way you can compare them to a state of the art LeCroy DSO like a WaveRunner 6Zi. This is like comparing a Commodore C64 to a Core i7 workstation. 2GS/s and 16kpts for a 500Mhz scope? And saving to a floppy drive (that is almost certainly dead after all these years)? Now really, the nineties are over.

content: QuoteThe 90's are over laready??? NOOOOOOO :-)grrr can't add the smiley faceDun't think anyone was comparing them to a $25K-$40K model. I was comparing them to ALL the current LCD versions being discussed in the forums.Yup, the FDD is loooong dead, but I still have GPIB and RS232 ports, which are enough in most cases. And I do like my built in printer.Also, it's 4channel with 500MHz analogue bandwith ! Plus 16MB of memory ... and I think you can still find a SD card option. SO for someone who has alimited budget, and DOESN'T need portability, or want to debug ALL the cr@p that the new scopes seem to be riddled with, then this is a BARGAIN !!

As pointed out before, the WaveJets are a good quality, but a little outdated Iwatsu design and the WaveAces are rebranded and overpriced Atten crap.Quote from: digsys on June 16, 2012, 10:47:18 amThis must be 16MB of internal storage, but as I understand the record length is limited to 16kPts. The CRT LeCroys we have at work are even worse. Something like 8kPts and only 200MSa/s for a 200MHz scope (swallow that, Shannon). This makes them unusable for most of the serious stuff.

content: QuoteNot sure what digsys has/was refering to - the 94xx series and the 9314 are not so good but 9354s have a minimum of 50kpts/channel sample memory, up to 2Mpts and up to 64M of RAM for processing, storing waveforms etc.Admittedly you can only get the full 2Gs/s by combining the four channels into one (though this does also mean minimum 200kpts) so not quite as good as a modern 500MHz 'scope which will normally do its full sample rate on all the channels simultaneously but there are still quite a number of 500MHz 'scopes in the Farnell catalogue which have 2Gs/s or 2.5Gs/s rates.The 9354/9374/9384 are 90's 'scopes but they aren't yet totally in the "only good to be put out to pasture" category.

I bought them pretty much when they werereleased, and there were only 2 in OZ. A govt agency (no names) borrowed one once for a "job" :-) They had an custom antennae that they attached,and could drive around and SEE what was on any VGA CRT screen, inside a building (but near a window).

content: QuoteAbolute bargains to be had on ebay :-) .. The RTC battery is easy fixed. I removed the PCB mounted one, found a close eqivalent, soldered flying leadsand a made a plug on the PCB. Now I have a standard swap out for all my CROs. The other big issue is screen burn in. I did find an ebay seller a whileago who had (has?) brand new CRTs, and quite cheap. Easy to fit. Swapped out a FDD once, no issue. Definitely NOT worth it now, besides we havedirect port connections. I've tried replacements, but the screen SIZE and resolution is hard to beat.

content: RTC battery is mostly sorted, have found a close item from Farnell - physically a bit smaller, 65mAh rather than 90 but will fit PCB.However an odd thing happened when I swapped it into the 9354T (the TM's battery is OK as it happens) - put new battery in and the 'scope wouldn't boot, fiddled around a bit including putting the old battery back but no joy. Left the 'scope on the bench overnight and mysteriously it booted fine the next day. I might have another go with a couple of flying leads to a backup even though the current battery is dead.Encoders: It's the two "zoom" encoder shafts which are snapped, These are Bourns "ECW" series, one with detent "clicks" and one with a smooth non-detent action. Mouser stock the non-detent version but the detent version is a special order item with a MOQ of 300. Wound up with two of the detent version with 6mm shafts. ebay not much joy here in UK so might as well buy from Mouser as their shipping is reasonable.Knobs - can't find anything which fits the .185" split shaft anywhere in the UK, or indeed anywhere; yes did try ebay. This is partly the reason I got the "wrong" shafts on the encoders. Found some OKW knobs from Conrad which aren't too far off. Slightly broader at the base (14.5mm vs 12mm approx) and a slightly different grey but I think they'll look OK.Floppy: not sure I'll put a lot of energy into fixing the floppies. The 9345T drive works but doesn't pass the built-in test. Have tried new disks in case my 20 year old, alternately baked and frozen in the garage ones were shot but no joy. Also tried a different drive (still have a couple lying around) but much the same. Might swap the controller card from the 9354TM but that's about as far as I'll take it. The drive on the 9345TM is toast (sounds like the spindle lubrication has gone sticky).I just need to find some time to get the old panel out and fit the new bits to it.

If you look closely, at the beginning of the video it was set to 50s/div, later the auto-mode changed it to something a lot smaller and the boot screen disappeared as usual. I'll have to verify this later.It may not strictly be a bug, but it is still pretty darn idiotic for the boot screen to wait until such an extremely long sweep is over. Why does it even start a sweep before the boot screen is gone? Thinking about it again, it fits into the whole picture of this device. It definitely has not seen any in depth testing... I'm certain of that fact.I think I will test my next scope in person before handing over the money. And if I should ever find a pot of gold (or equivalent) somewhere... I WILL get a Chainsaw and cut this darn thing in half.

There's got to be enough people out there to start a shit-storm.To get an Agilent with the same specs (4CH, 200MHz) I guess I would have to shell out at least 5k€ or thereabouts. And that probably wouldn't give me protocol decoding. Not that I desperately need it, but it's a nice feature. But they just love to charge you through the nose for those extras.

I had a phone conversation with a nice sounding lady and there was a 'slight' misunderstanding. It turns out I was talking to the boss' daughter. Then their boss gave our 'big boss' a phone call... On the next exhibition I met 'her' and instantly changed direction. Fortuitously I had removed my name-badge before she could've read it.

Support people don't know their own products. Good support is something else.Quote from: madworm on July 07, 2012, 03:28:59 amIn the ~2k€ range and 4ch league there's more or less only the HMO2024 and the Rigol DS4014.Yet if you need protocol decoding, this gets very expensive for the Rigol.The HMO2024 is a neat little (in the most verbatim sense) scope. Not perfect, but no major show stoppers. E.g. interleaving in 2ch mode (->2MPts/Ch) works only for 2GSa/s which means timebases <= 50µs. When reducing the horizontal resolution to >=100µs, it jumps directly to 500MSa/s and 1Mpts/ch (-> no benefit any more from 2ch mode). Also you can't save full waveforms with the scope, only via the PC tool (which is very basic). And yeah the small rotary knobs feel a little cheap.Anyway, all the base functionality works very well and there are some neat features. Also the probes are detected automatically.

content: Quote from: madworm on July 07, 2012, 10:34:18 pmI think it is legit as I was given the link by Agilent after asking about a refurbished item advertised on their UK web-site, they basically said all their refurbished items go through the e-bay store.Some of them carry a three year warranty (though this seems to vary) and are calibrated so, though I share your concerns regarding e-bay, it is probably ok. Anyway, I'm not pushing it - I have no connection with Agilent and I think though the hardware is discounted the software add-ons are probably full price in which case you could end up paying more for the decoding than for the scope! (I don't know this for certain as I've not made any enquiries), for instance the decode option for one protocol on the 5000 series is over £1k!I continue to dither on an oscilloscope. The decoding options seem to be very expensive except for the Hameg or Rigol 2000 series but then even with the Hameg if you go for the digital channels as well the cost approaches that of say buying the LeCroy LogicStudio separately and the Rigol 2000 series is only 2 channel so decoding is rather limited anyway.

The Certiprime stuff has a normal Agilent warranty (3 years? , maybe depends on the product).The rest you are on your own, but I believe they fully test everything before sending it out and they have a 7 day (see item description) return policy.I believe they actually are part of Agilent, and believe it or not those prices are heavily discounted.Not much there for a couple thousand euro though.

content: IMO unless you REALLY want the protocol based trigger in there it's better to use your usual choice of USB LA's. I generally only use the MSO bit as part of signal timing and integrity analysis. MSO were never meant to replace LA's.And remember you can always use a separate MCU to provide the protocol trigger by pulling a pin when the right packet is received.

The Agilent 2000X is too limited, the 3000X too expensive.

It's been a while since I've sent them my reply to their refund offer. Maybe they need some more time to process that... or they have an overzealous spam filter.It's still in mint condition. It's even got the protective foil on the LCD screen. Only one ground cable has had it - probably material fatigue in the alligator clip.As the issues with it are clearly due to its 'magnificent' firmware, I feel somewhat reluctant to punish the hardware by cutting it in half.

The option to upgrade the bandwidth to 500MHz might come in handy later.For personal use I can't justify the expenses of any of the Agilent ones with similar specs. The 2000X series is cheaper, but also much more limited. I can get more bang for the buck elsewhere. 50000 waveforms/s is nice, but not everything.Currently I'm happy to get the extra money into my bank account and will probably go for the Hameg HMO2024 at some point. Upgrading to mixed signal is affordable and I can do that later. It's a German company, so I don't expect to have any issues with unreachable support.

I guess if you are going to fully option it out then it might come in cheaper in the end.I think if the DSOX3000 series did not exist it would make the DSOX2000 series look a lot better. People don't like knowing their scope has been limited. I know it would bug me quite a bit to have bought a 70mhz X2004 and know that it is just a few software bits keeping it from being 200mhz.

But to me it looks like it has been cut down artificially - and quite a bit too much IMO. And the options are waaay too costly for me.In one of Dave's videos it was shown that the 2000 series shares the button layout with the 3000 series. As a result of this pressing an 'unused' button causes stuff like "This option is not available... blah blah blah", which is enough reason for me NOT to buy it.

You know the good stuff is under the hood, but Porsche wants $20,000 to turn on the additional 200 or whatever HP. Agravating.I am hoping that eventually some of the options on the x3000 (and x2000) are offered cheaper. Maybe in a year or two after they have recooped some development costs they can offer a combo package to current owners to fully option out their scopes for something less than insanity $.
