Arrived today, a cheap DC switching supply...
Good display, good display/output accuracy, slim fit.
Available in three versions, 0-30, 0-60 and even 0-120V, this is the 120V version.
These Jesverty thingies are interesting. Basically
I am in the market for
dual 0-120 V 100 mA
(maybe even with a bit more umpf)
lab supply which will not cost an arm and a leg.
Intend use: High voltage Opamps. Since these Jesverties
apparently do not have a control input of some sort
,
I would have to improvise to gang two such units.
Almost there. Maybe some day these things will sport
an USB control input.
Anyway, thanks for the heads up.
Remember to buy the model with the powerful inner core like I did
Also check and see if the output floats high relative to earth to avoid any surprises.
Some nostalgia, a Micronta 22-204A.

Which costs more, the compact power supply or pair of Hirschmann banana test leads?
I found a hp3456a in working order.

I LOVE mine.
Not only is it gorgeous to look at but the math features are amazing; specifically the "(X-Z)/Y" and "100(X-Y)/Y" functions.
Although the meter does not offer a current post, you can first measure a small shunt (via 4-wire) then store that in register Y (STORE, 8 buttons). Attach probes across the shunt then enable "(X-Z)/Y" via MATH,7 buttons to show current directly!
Also, I'm currently exploring the "(X-Z)/Y" function to directly read ESR! By (a) setting my FG to produce 1Vpp +0.5Voffset 200KHz square wave, 50R output Z, (b) the cap under test across the FG output, (c) a 100n cap (A/C coupling) to the 3456A set to ~V, (d) Y register set to the magic constant 0.006400, (e) then enable "(X-Z)/Y" via MATH,7 buttons to read out ohms directly.
Need to sort 10K resistors? Just punch in 10000 STORE 8 to save 10000 in register Y. Enable "100(X-Y)/Y" via MATH,8 buttons, then proceed to measure your resistors. The display shows % error directly. Easy peasy!
Can't wait to buy a bunch of thermistors to play with the THMS*C function too.
Finally....
Oh, and not the Logitech, not the table, not the LP mess, but the Quad
I got a Ti-89 Titanium used for $20 Canadian, and immediately flashed it to os version 3.10 using Linux TILP. Also I continue to mess with an Odroid C1+ that I got for $20 used with a 16GB SD card. I am still looking into it but it seemed to fail with certain SD cards on cold cold boot, but seems to be working with a certain SD card so far.
Well, I guess I technically didn't "buy" this, but I'm pretty sure I'm the first person to have one

NPA stands for Network Problem Analyzer, I guess ?
(laughs) Good guess. Actually, we have a software feature in our cellular network drive test analyzers (ROMES/TSMx) called "NPA" and it does stand for "network problem analyzer," but that's not this
https://www.rohde-schwarz.com/us/manual/r-s-romes-npa-user-manual-manuals_78701-117121.htmlWe do have a scheme for at least the first letter of our three-letter product names: F for spectrum analyzers, S for signal generators, Z for network analyzers (get it?), C for communications testers, etc. N normally is used for power supplies (Netzgerät), so that might be a clue ... although this is not a power supply
We're launching it in a few weeks, so I'll be able to talk more about it then. Every time the FedEx driver drops off a new instrument, it feels like Christmas morning to me, so I wanted to share what (little) I could.

It's nice to have more Christmas mornings with a new device during the year 🤔 I can only buy the box in which the device is packed at most 😂

Beautiful piece, congratulations 👍 I bought a 6 1/2 DMM 2015 THD last year

Thanks! I had a second hand K2000 too, and really liked it. Though it started to slightly drift out of alignment with everything else in the lab.
Getting a full calibration done for the K2000 would cost more than what I paid for it, so I decided to bite the bullet and get the DMM6500. Very happy with it so far!

And you won't regret it. Other than the annoying long boot time, it's an absolute pleasure to work with.

I've bought a Vintage Keuffel & Esser K & E: N4080-3 LOG LOG DUPLEX TRIG Slide Rule With Case from the USA.

I also bought the DMM 2015 used, but from the service of measuring technology, so I have it adjusted.
I would also buy one, but I have to replace the oscilloscope first, so I'm saving up, I'd like an SMU 2461 - but I'd have to sell my body box for organs
Congratulations on your purchase and may it serve you well
GPIB breakout box for a ... project ... I'm working on
