HP 6114a precision PSU
I'm still mulling over whether to disassemble and clean the decade switches, though at this point, I'm leaning towards putting it together and power testing.
From few years ago from ebay for $300. HP 3586A Selective Level Meter. Seller said that it is new never used, all its life spent in some storage of Canadian Navy.
On bad note: I saw it arriving in UPS truck (tall truck!) and 2 guys were unloading the box and it fell on the ground! Hate this guys
Did the 3586A survive the shipping abuse?

I'm still mulling over whether to disassemble and clean the decade switches, though at this point, I'm leaning towards putting it together and power testing.Suggest taking the wheel switches apart and give them a good cleaning. When these switches are noisy, problems with the output can occur.
That entire area must be really clean as leakage paths can also result in problems.

After seeing a lot of scores here, some of which made me a bit jealous , I have scored some nice equipement yesterday.
At my uni they had some RF related test en measurement gear they want to get rid off. I've made them an offer and to my surprise they said 'Oke'
Here is my score:
- HP 8590A Spectrum analyzer - 10kHz-1.5GHz
- HP 5315B Universal counter - up to 100MHz
- R&S AFG Function generator - 10mHz-20MHz
- R&S SMP02 Signal generator - 2GHz-20GHz
I've tested them all and as far as I can see they are all working as advertised and are within specs.
To make the story almost to good to believe...... I only paid €345,- for the lot.
For all equipement I've found manuals except for the R&S AFG so if anyone has this as pdf, would you be so kind to share?

Thanks.
It seems to be working Ok at first blush. I'm going to calibrate it and then check more closely. I'd rather not take the switches apart if I don't have to. They aren't made for disassembly, and even if they were, it brings a new risk of breaking something. I already have enough things to fix that don't work at all.
QuoteA few small adjustments and the 6114a is appropriately accurate on most settings. 10mv decade is a bit inconsistent and noisy though. Next step will be cleaning the board of any flux residue from when I removed and then reattached it. I'd really like a 10-turn pot for the low adjustment too, but that seems a tall order.
Do check for possible residual paths that can be causing the observed noise. Use high purity (electronics grade or similar) Isopropyl alcohol. Lower purity solvents can leave residuals causing problems.
Been there done this, when those switches get noisy, the set low range accuracy suffers and the output can be noisy too. That 10 turn pot works when all is well. These are good precision power supplies.

In other news, this weekends OMG buy is a EDC 521 programmable DC calibrator for $150 "from a working environment." The seller has some other EDC gear listed, though not at as low a price. It's all listed in the wrong category, and its kind of chance that I saw any of it.
Those pictures are familiar. Does it happen to be HAN university of applied sciences in Arnhem, Netherlands?
If so: you lucky man. I thought of making an offer but they also said they already had a company buying the lot. That SA alone goes for more than twice on eBay than what you paid for the lot... <insert green face here>
Still: congrats!
The R&S SMP02 is probably the most expensive unit in the score. Easily more than 2000$,if you find someone who needs it. US ebay has them listed between 5-17k$ and you get it for 350€, holy shit
I'm still looking for something comparable to realign the YIG input filters of some HP 8566s that I'm rebuilding. Wish I could get one for 350€
