On the first look this does not seem to be TE related, but I did make a cheap catch at 20€ for this assortment of crimp contacts for various Mil connectors. Most are 26482 and 38999 luckily, where I'm fully equipped with tooling.

TE related it is, because a lot of them will go into the production of adaptors, so that I do not have to sell someones organs because POMONA.

And Shakalnokturn did just prove that I was wrong. The one I'm after is not the B1024, but the B1023.
So we have the following Designations:
1st Series
B1020 (no buttons - no additional functions, no RMS) Gossen: ????, Norma: ????
B1021 (8 buttons - Hold, MinMax, manual range, RMS?) Gossen: MAVO20, Norma: MP12
B1022 (15 buttons - as above, +dB, Limits, frequency and type K temp., RMS) Gossen: MAVO30, Norma: MP13
B1023 (15 buttons - as above, + time recording, RMS) Gossen: ????, Norma: MP14

The B1022 and the B1023 are distinguishable by the second pushbutton from the right in the lowest row, which is only +/- on the 1022 and has a shift function 'Time' on the B1023) And 'Time' does not mean merely elapsed time, but you can set a RTC and any min/max event or limit violation will be recorded with the time of occurrence.
THAT is the function I'm after. And now we know that I don't get it with the MAVO30. :( :(

then came a second series in the same form factor:
B1024, which has 4 pushbuttons and no current range, but a special range for current clamps with voltage output. It could also do temperature by PT100 and AC voltage with 1kOhm/V.
B1025, which has 6 pushbuttons, normal current ranges and all of the above plus min/max, and a range for current clamps with current output.
B1026, with 7 pushbuttons, RMS, all of the above + frequency, capacitance and a backlight.
B1027, which I do not know
B1028, with 11 pushbuttons, TRMS, all of the above, plus relative, limits and a zoom function for the bargraph.

I do not know, whether there were Norma/Gossen equivalents to those later ones. There is a Norma DMM950 with the same form factor, which has 12 PB. Here is some additional info:
https://sigrok.org/wiki/Norma_DM950
but that can't be totally correct regarding the equivalencies.
Remarks:
The first series was listed in the Siemens catalogue of 1987, together with the new analogue/digital hybrid B1012.
The Gossen models were all BEFORE Gossen did go together with Metrawatt.
The later series is often seen with a rubber protector, the earlier ones not.

Just nabbed two more boat anchors from Yahoo Auctions.

A HP 4140B pA Meter/DC Voltage Source just because it looked interesting, and a HP 3325A with options 001 (Ovenised Oscillator) and 002 (High Voltage output).

(Photos from the auction listings)

And the catch of the day is this Swiss-made E12 resistor sustitution box (not a 'decade' in the proper sense, but going to be useful anyway.) Especially as they claim it to be 2W and 0.5%.
Sadly, I missed out on a Tektronix differential preamp.

After a bit of a kerfluffle with FedEx delivering it to the wrong house, a very nice HP 1727A storage oscilloscope. Had a chance to exercise it and everything appears to be in excellent working order. In the pouch is the print operating and service manual and user's guide too!

I saw that one on ebay and forgot to bid!

I found a nice HP 438A power meter - refurbished and calibrated for US $115.  Now, if I could find a similar deal for those 84XX power sensors.

Picked up an 8558b spec/an for $80 bucks. The fingers on the switches need repair, but otherwise a very clean unit. Don't hold your breath for immediate repair postings, this one is going on the "to do" shelf for a while.

Oh well...some adaptors - and proper ones, so some crappy ones can be shed or relegated to the reserves.
And some splitter/combiners, with a frequency doubler coming as 'bycatch'. Only MiniCircuits, so no reason to be envious. ;)

More HP junk.....

Won an auction on a 4145A Semiconductor Parameter Analyzer with a 7475A pen plotter for 3700yen. (Photo is from the auction).

Both should provide hours of entertainment to restore.  :-BROKE  :-/O I'll have to figure out a measurement jig for the analyzer, or buy the official one from somewhere.

Wow, that's quite a score. Less than US$35. :o

A month or so ago, I saw that you can still get pens for these plotters. I haven't tried any, yet.

Funny that someone substituted a black Teac floppy drive in the analyzer.

We have a Sony-Tektronix 371 curve tracer. Absolute beast, and impossible to kill.

Dead mechanical switches? No worries, just replace with a new one.

Dead front panel? No problems, GPIB+LabView solves it.

Dead fixtures? Not a thing. We made our own Kelvin fixtures.

I'm building a higher voltage one to replace it, but before that, it remains to be its own legend.

Yeah, should be fun to play with.
NOS pens are still available at good prices on ebay, so I'll probably pick up a set of colours soon.
Also, I plan to replace the disk drive with an SD Card emulator. I also saw a colour LCD display replacement, but at $400 a pop, they are a little too pricey....

I also have a Tek 577-177 curve tracer, to restore, so I'll have to decide on which to keep... The minister of finance is eyeing off the resale value of them. :D

I see those pop up on Yahoo Japan every now and then, one sold just the other week. They still sell for around $2k though..
Being able to get the data out via the disk drive is a handy feature though.

TIB a boxful of random bits from an auction. £50.
I bid on it because there was a national instruments gpib-usb-hs adapter, so that was a win to start with.
But I also discovered :
  • An Axis PTZ dome camera
  • 3 raspberry pis (3B), two of them with the 'official' 7" LCD touchscreen and power supplies
  • A TP-link router
  • 2 POE taps
  • a thermocouple temperature display
  • random connectors and components

This box just came in. Unbelievable how flat that thing is - the box is just 20mm high! The large and comfortable knob adds about the same. The switch positions are crisp and totally aligned with the panel marks. I like it already.

Just bought a Philips PM5518-TX colour TV pattern generator today for just under 3000yen.
I've already got one of these but it is missing the RGB-output option, which this new one has.
The new one is in a little more worn condition, so I'll make one good one with all the features from the two, and the other will be sold in working condition.

So, in the age of digital TV, what will you be using this for? I've been wondering for a while and now can ask someone who owns one (well, two).

Useful for people who like to restore old TVs.


Couple of guys I sub to on youtube who I've seen using analog TV signal/pattern generators:

I guess I should share my latest "scores" here as well.

1) Lucent RFTG frequency references, both OCXO (left) and rubidium (right). It's designed to fail over to the rubidium standard if GPS lock is lost for any reason. I need to find a suitable power supply for it as well as perform the relatively simple mod to get 10 MHz ref out directly on the front panel (old telecom stuff like AMPS, which is one place this might have been used, uses 15 MHz apparently).

2) HP 8405A Vector Voltmeter. Absolutely pristine condition. Came with a nearly complete and hard to find probe accessory kit. Probes are not burned up. Paper manual and schematics too! This is a direct predecessor to the first network analyzers HP made, and can be used for a lot of similar tasks up to 1 GHz.

3) HP 8640B sig gen. Also in amazing condition, fully functional front panel. Has Opt 002 (512-1024 MHz output with reduced RF power). Also came with manuals.

Yeah, I like to collect old CRT's (small ones, like from portable TV's, camcorder viewfinders, etc) so I use this sig gen to test and align them.

I want the RGB output option so I can find and test direct RGB input into the colour CRT's I have, then my plan is to use one of those ebay HDMI or VGA to RGB converter boxes to convert old mini colour CRTs to HDMI/VGA/etc.
Will make for nice raspi screens for retropi or custom retro monitors for vintage PC's.

In some parts of the US, there are actually still low power analog TV stations hanging on (definitely not mainstream networks though). Other than that, gotta have one of those converter boxes handy if you want to actually use the damn thing.  :-DD
