My apologies to those I offended but more importantly to those who wanted to buy the gear but now cannot. This lot was the worst buy I have made so far as it is not worth the trouble and BS I have received.I will not start another thread under this tab.

Flog them and buy a single more bench/SWMBO friendly 34401A

I think with six dials and a 5V range the best you get is there. Or are you looking at AC ripple noise on the output?Hmmmm, it does do 5mA full scale, so it does do 10nA resolution, which is pretty darn impressive.

content: Quote from: Inverted18650 on January 18, 2019, 07:15:45 amJust an FYI here - Minimum frequency for the 8484A is 10MHz and the Boonton is a 1MHz output so that will impact the reading. In the 8480 series of sensors you want an 8482 as it covers 1MHz. I'm not sure how far out the 8484A will be as while I have 8484A's I also have 8482A's for below 10MHz.Unit looks in good condition though - Please PM me if you can't come to agreement with 4thDoctor on a price for the unit as I think it might be useful for my Dad in his wireless shack (I also have a 432A-H76 so I can set the 50MHz output on the power meters directly).Good luck with the rest of the gear.TonyG

If you have option 002 (it will usually be marked on the back of the unit) then you can also do amplitude checking up the 18GHz limit with that unit - Again, mine was good enough for government work even after all these years (no where near as accurate as my 8480 series sensors etc though).One suggestion that might help move the gear is to check on eBay for what these items have actually sold for (not the asked price, use the sold/completed values) and set an initial price there.TonyG** There is a guy rebuilding front ends but I can't remember if he is still doing it etc

content: You don't have a Yaesu FT-817 in all that do you? The 857 is more power than I want as I have a 991A. The photo of the big stack of gear along the wall really didn't provide a way of telling what you had for sale.My biggest problem is over the past 18 months I've already bought about $12K of gear and I've pretty much run out of space. I'd like to get a 2nd 3478A so I can monitor both voltage and current, but after that it starts getting rather self indulgent. I've got a pair of 34401As, so the 3478As are just for monitoring the power to a device from the PSU which only reads to 4 digits.I'd love to have the resistance standards, but just no way I could justify spending what they are worth.

content: The fluke 3330B, the reason the output is not latching is probably the electrolytics on the current limit board, at least that's what was wrong with mine. Pretty much every electrolytic is bad.If you want to get people to drool a little more, check the voltage coming out of the zener reference board, it's in the left row of boards (looking from the front) and has two 2mm banana jack's, red and black, on top to verify the 10V output, perfect for some multimeter probes...Also, just to check, but you did press down the security switches on the top and bottom of the case (normally held down by the case)? They also prevent you entering OPR

author: toastedcrumpets

timestamp: January 24, 2019, 08:51:39 am
content: So was it the electrolytics on the current limiter board then? I think the manual says you can even pull the board and run without it (but don't do that without double checking).Also, watch out for noise on the output (use your AC voltage mode on the DMM to measure this). One of the big black-cardboard covered electrolytics in the middle-back of the system (attached to the mainboard) went open circuit on mine and caused oscillations at the frequency of the pre-regulator. I still have some noise from the chopper due to some bad electrolytics on the regulator board which I couldn't replace yet. It is a game of wackamole hunting down sources of noise but I'm nearly done!

content: I think there's another lesson .... grab every little bit at the first visit. I might go so far as to sweep the floor and sort out the wheat from the chaff (and dust) later. I know it's extra time and effort requiring a bit more space (which you may not have had at the time), but it gets around this problem.I wouldn't be at all surprised if they had already swept the area out and tossed anything they felt was useless. It may be that since they had cleared the bulk and got enough for the stuff you took, that they would be happy to dump the shrapnel.Of course, there's always the possibility that there could be a legitimate reason why they haven't got back to you yet - and we can only cross our fingers for you. It would be an extra gesture on their part to honour Grandpa's gear in its finding new homes and purpose.Edit:Just read what you posted in the TEA thread.

content: I'll give you my personal situation and my overall take and advice.1. I am still mulling a purchase. But there is nothing there on my have to have list, and the prices aren't forcing me to buy. The prices are fair, but not going to make me buy just cuz it is too good a deal to pass up. I am sympathetic to helping you get out of the hole you have dug trying to help someone out so there is that factoring in my decision. On top of that I am off to visit family in a day or two so won't try to pull the trigger on anything until I get back in a few weeks.2. Patience will be required. Lots of it. If you search the buy sell list for my handle you will find a large lot of gear that is available. You will also find how long it has been there and will find a hint at how much has sold. Far more has been sold on Ebay than on this forum. And prices are not comprehensible to me. Things I think are of low value have sold quickly at relatively high prices. Other things which seem to have a solid value based on sales have languished for months with no takers even when the price is reduced to a third of the established sold price. This has been a multi-year journey for me.One thing which has become obvious. If the item you are selling has a tie in to the drug world it will sell fairly quickly and at high prices. Precision scales, lab heaters and other chemistry equipment has sold far better than purely electronics gear. Of course that also creates an ethical dilemma. And I don't have any advice or ideas for how to tie the gear you have into that market.

So, it's good having this here with what's available.Changing this thread's title to be more about the kind of gear available (RF, calibration, vintage, etc.) would be beneficial for catching the eye of those passing by who may have an interest, but wouldn't otherwise click to see what's inside "grandpa's lot".

content: I think the price list is a must if you want to move things in a timely manner. Adding OBO to items where you have some room will help as well. I sometimes will buy something I don't really need because the price was too good to pass up. I don't have a lot of experience in used T&M equip, but if I see the word "Calibrated" and nothing else, I would expect it to have an in-date cal sticker on it, but I maybe be just being naive. Best of luck.

content: Quote from: beanflying on February 04, 2019, 02:12:26 amI'm just enjoying seeing all the stuff being presented.I wouldn't mind a 3456A, but I can't afford it, it's too big for my current work area - and, to be honest, is far more meter than I need (although 4 wire measurement capability would be nice). Same can be said for a couple of other things.My needs are mainly vicarious and are being well satisfied just browsing through this thread...

I recently grabbed a load of test equipment and need to work through fixing it and installing it...By set I meant I'm the guy who got the resistor standards and most of the inductors and capacitance standard too once I finish paying for them.

I just bought a fully working 66311B for £100, but ago keysight tell me it's worth thousands 😁.As I don't really need it, just wanted to add it to the standards, I'm happy to see it sold to fund inverted's TEA or given to someone who can make a better case for it!

Not even sure if Bridge measurements are still taught more than in passing anymore@Conrad Hoffman springs to mind as someone who may have an idea for a good home including his own

content: I believe the temperature calibration standards still require the use of a bridge, at least that's according to a researcher I know who helped redefine the Boltzmann constant a decade or so ago. I told him I had a DMM7510 and he was very excited but was sort-of disappointed with its resistance range (!), as temperature work requires more precision.
