Racal Dana 1998 Universal Counter, this one has the 04E option installed, the high-stability ocxo. It's not been calibrated in a while but I will use a friends gpsdo to adjust it.

Mine hadn't been calibrated for well over a decade, when they say high stability, they mean it, it was millihertz off :)

Just scored a small Nicolet Scientific Corporation 444A "Mini-Ubiquitous Real-Time Spectrum Analyzer" for 35 Bucks. Doesn't switch on, so I hope for an easy repair.

Funny how we now use the term "Real time spectrum analyzer" for todays expensive fancy spectrum analyzers that do FFT on the IF for providing crazy fast sweep speeds.

Please post a photo when the device is on (if/when you fix it, you can use Russian flux :)). I'm curious to see what it can do.

I may post a repair log for that thing :) Right now I am waiting for it to arrive.

I introduced "Dana" to Lady Heather and the girls were quite in tune. Just a smidgen under on the last digit [emoji6] Only took Dana an hour or so to warm up to her new acquaintance.

Yeah, I like mine, good, solid counters.

One thing it took me a little while to find, press and hold the up arrow key and it'll select the 20S gate time for the extra accuracy if that's something you need.

Ah, that is a good hint. I was already wondering how that would work. Thanks a ton!

Yesterday it arrived "safely" (was thrown over the fence by DPD and dug itself 15cm deep into the ground. Idiots!). Initial very short test (it's just to hot in the lab to do any real work) showed the fans working and the High voltage for the CRT being generated, but no sign of life other than that. Not even the Power LED turned on. I am strongly thinking it may be just a power supply issue. Wish me luck :)

And by the way: The russian flux is great, I especially like the honey-like orange one.

Ask-155-vc, the one that is water-soluble?? It's pure evil, must be thoroughly cleaned or it will destroy the board, wires, everything.

No, I was talking about FN-255 PRO. I have no idea about the specs though, it just works for me and cleaning is always done afterwards.

Cool, that one has the highest resistance, approved (by the manufacturer, no independent tests) for precision and high-voltage circuits. It's also the least active (=worst soldering), actually. E-700 Pro solders better. I mostly use fn-255 pro as it's sort of safe in all situations.

Not really a score, but I did pick up a KKMOON 60 MHz function generator for $85 shipped from China.  That was cheap enough for me to try one.  Now I sit, thinking to myself, 'One must have patience, Grasshopper.'

Is that the FY6800 based one?  I really like mine - it does enough things that my IG5218 and Wavetek don't, to find periodic use.

It is. I am looking forward to playing with it.

Since I must have acquired a really bad case of TEA, I placed a bid on a governmental sales of a TDS8000 sampling oscilloscope that supposedly had been used in a scientific research facility and was offered non-functional...whatever that means. I was quite surprised when I received a letter (yes, by snail-mail  :o) from the sales organization with an invoice, confirming that I got the deal! 300EUR plus tax.

I picked up the instrument which came with all the documentation, software CDs and one 50GHz sampling module included (this alone will outweigh the spendings substantially if I should decide to sell), and was clean as a whiste, not even "real" dust on the fans or inside, and as expected, found all of the three memory backup batteries to be flat. Batteries replaced, instrument calibrated, and still after power cycling I get the error of faulty NVRAM data integrity and another message that relates to calibration data incoherency. So probably I've got to replace that crappy Dallas / Maxim NVRAM module on the acquisition board which seems to fail just too frequently to be coincidence. Anyway, after calibration and without power cycling the instrument, it performs quite well.

Do I really need this monster? Surely not! But it's quite some fun to be able to enter these frequency ranges to actually qualify and quantify fast edges and high frequency signals. Since my version still came with the Windows 98 operating system, and there seems to be improved system software available for an XP O/S equipped version, this update will be next. Fortunately, the instrument came with the latest PC motherboard that should permit this update without too much hassle (I hope...).

Anyway, who can claim that he can measure rise times of 30ps... ?  8)

Cheers,
Thomas

Now that is an impressive deal for 300 bucks.

I had to pay that much just for the plugin module on my HP sampling scope.

Quite a deal, indeed! Nice one, Tom.

So I rolled the dice and seems I need to do a little repair job or two. :-- $400 USD landed on my door from the USA and only $40 of that with evilbay global for freight instead of $120 cost (seller screwup) :-+ So off to the 'shelf' until I find it some time for a little loving and some power.

Valhalla 2500-EP Current Amplifier.

Relay Daughter board has broken stand offs and seems to have relied on the wire and tracks for one of the mounts regardless :horse: :palm:

Shipping hit to the side frame to be taken up with the seller or just suck it up but worst case some gentle heat and clamping will likely take it out. Much less work than my 740B Handle welding job.

Does this mean that you have set your sights on a Valhalla multipurpose calibrator? Or is it already underway?

At 'this stage' the Fluke 335D and Valhalla 2703 with this one will do me to AC/DC and I calibration gear. In reality for anything I do now or am planning to make over the next few years is covered but a 3458A later in the year might be in my sights ;)

Got this Toellner Lab power supply from the evil bay. Description said "untested and for parts only", picture showed a pretty much beaten up unit.
Made a lowball offer, and got this:

It's a dual channel 32V / 5A (each channel) supply - and yes it worked out of the box. Needs some slaps with a hammer to make the covers fit again, and new encoders. Will have to figure out how to remove the front panel PCB to see what type they are and then order some new ones.

From my experience, Toellner makes pretty good lab supplies, and some other interesting stuff, so I'm quite happy with it.

What I don't like - they mount a lot of parts using blind rivets. Hope I don't encounter one when removing the front PCB.

Lucky you, I like the build of this supply. I hadn't heard of Toellner until recently when I stumbled on a F.G. looking for something else.
Would you say they're a kind of Bang & Olufsen of T.E?
