Picked up a 10G ohm 10kV voltage divider. It was bit of a gamble as Unilab is an educational equipment brand but opening it up revealed some decent quality Welwyn 2% resistors. I bought it because of the difficulty of finding 9G, 900M etc resistors.
I have a pile of those Welwyns I salvaged from an old AVO meter. Some 20M, 14M, 1M0 and 700k all in the high voltage inputs (rated for 3kV). I have never seen actual G ohm resistors before.
Picked this up for $155 (!!!) Canadian dollars. Couldn't be happier!
Well done, very good price !
And in nice shape, really good
Today I got my Anritsu MS2683A spectrum analyzer from Japan (about 800USD including EMS).
I thought that I should do a mini teardown, BUT I changed my mind after I removed the case.
A drill for drilling holes into walls. Normal price 69€, Tesco Slovakia blew the last three out for 15€ each. Thought: nothing to lose here...
Also got a Micro Strip fiber stripper. I'm tortured enough by my Miller stripper -- it nicks and breaks my fiber so often that it is practically useless. People always say a Miller stripper needs proper training to use, and it seems to be true.
I didn't know what the Miller stripper was so I searched - this is what Bing told me: Your current Bing SafeSearch setting filters out results that might return adult content.
Naughtiness didn't even occur to me... I'm a nerd I guess.
Second hand TTI 1705. £46 on EBay. I received it a few weeks ago but haven't had much time to use it so far.
I've gotten a few goodies recently,
A few textbooks I have bought are Fluke's Calibration : Philosophy in practice. The hardcover is in pretty average condition, but all the pages look to be really good.
Another textbook is Resistor Theory and Technology by Felix Zandman (Founder of Vishay)
I also purchased a nice looking set of Dana current shunts. They are a similar concept to the Agilent 34330A, but there are 6 of them in a wooden case. The resistances range from 0.1R through to 10K000
I will post some photos when they arrive, I cannot find much info on them other that this from the 1984/1985 instrument catalog

The Model 651 Current Shunt Set consists of six
precision shunt assemblies designed to plug into the
input terminals of a digital voltmeter. Each shunt is
clearly marked with the full-scale range that is
established for the DVM. All six are packaged in a
wooden box lined with formed foam to prevent loss or
damage of the shunts.

A BK Precision 1698 Power supply. User interface is absolutely not friendly, but I'm happy, got it for 90 EUR and it is in very good condition.
Only the red little thing is missing on the + banana plug (but that's not a big problem). It works fine.
I am assuming the behaviour of the 1698 is similar to this 1697...
Yes, it is the same, but I have the
decoder user manual.
Sure that Shift + 0 + 3 digits + enter... to set maximum voltage output is not... user friendly. RTFM : read the
friendly manual.
I remember that challenge video. At least BK (or the OEM) is consistent with their wonky interface.
I think the price was ok (90 eur shipping included).
Sure : it is not a linear power supply, and interface is awful. But if I need some 48V, my other PSU stops at 30V, so this one may result useful.
But you are right.
A Solatron 7060 multimeter, bargin at £60
Sold my MSOX3104A, then bought an MSOX6004A. Net difference: $3.5k. Picked up in person. Driving 20+ hrs on I95 is not fun. And for the first time I know there are non-free interstates.
That sounds nuts, but a great way to spend $3.5k. I love my MSOX6004A! So easy to use, I don't even think about it. Well done.
Hello!
Finally I get my 53131a...
I wait for a Gerry OCXO and a Poland Prescaler...
It works very well... Only.. the display is dim...
I must test the DC-DC converter for 5.2V in filament and 43V for HI VOLTAGE.. Next week I will try it...
If not I cannot have the VFD... What a shame!!
Regards
Manuel
hmm... I was a fan of it since it came out:
And I love it. It also have the GPIB option... Pratically brand new...
