That thing isn't simply an AC millivoltmeter. It is a selective level meter, also called a frequency selective voltmeter. It is essentially a laboratory-grade radio receiver with a huge input level range (microvolts to volts without overloading), and a hyper-accurately calibrated "S-meter". If you hook the input to a longwire antenna, you can use the speaker to listen to frequencies from VLF up through HF. The major use of these was in telco central offices and the like, for checking various channels of carrier (FDM) systems. You can enter a specific frequency of interest, and measure the signal level at that specific frequency, while tuning out unwanted ones. A very specialized bit of gear, but lots of fun to play around with. I have an HP 3586C, which is similar in vintage, build quality, and functionality. This thing is a DEFINITE candidate for a repair and play around series. Manuals available free online ftb.ko4bb.com/getsimple/index.php?id=manuals&dir=06_Misc_Test_Equipment/Wandel_and_Goltermann

You can measure 3rd harmonic distortion on your LF/HF generator fx. at 1kHz then you adjust for 3kHz and measure the voltage at the desired bandwidth. Can also be used as SSB receiver. Please Dave, DO NOT CONSIDER THIS AS "just a milivoltmeter"... this is MUCH more than that. Please !! is is a measuring receiver, very high quality measuring receiver.

The reason it's designed so modular might stem from the philosophy in the 70s in Germany that devices had to be repairable. Companies were actually investing a lot of money into a dense service network and advertised their quick turnaround times when their devices had to be repaired (that's WHEN, not IF!). According to my dad, a transistorized TV had to be serviced at least twice in its first year of operation. Japanese manufacturers at first had a really hard time to come into the market because people were afraid they wouldn't be able to have their devices repaired. Took quite a while until they realized that those devices just didn't require maintenance. :D German manufacturers started their downfall right then and there. That being said, now it's time to show how easy this modular construction actually makes repairing and servicing it and get it back to life. :D

yeah yeah.... "a millivoltmeter"? That's not even nearly a millivoltmeter but in fact is a measuring receiver - kind of spectrum analyzer where you get an calibrated readout of the signal voltage at *exactly* the specific frequency you tuned in. And even if one might use the instrument in fact to hear some AM modulated SW radio stations it's intended use is to identify the source of any "signal" on a measured object, line or whatever. An experienced operator could determine from the sound of the hum or noise if it is some wanted signal, some hum from any power source being coupled in, some radio interference from a nearby situated radio station or whatever. In the hands of a well trained person this beast could be a real sharp knife to analyze and eliminate unwanted interferences. For Joe Blow it would be only some overrated millivoltmeter that does not even have some working beeper for continuity tests or a transistor tester...

I have an old Wandel & Goltermann catalogue, it's a hardcover book that doesn't have list prices so I guess they were not cheap xD You could also purchase a PS-19 level generator which could be used together with the SPM-19. W&G build a number of selective level meters but they are hard to find because they are still very useful and thus valuable since simular instruments are no longer build.

I did a teardown video of this one 3 years ago. I think it was BEB #1 or so ... Usually you pull-out the complete mainframe once you have removed the top plate cover. The mainframe is not screwed down. It' s just sitting in the aluminium enclosure, in rails. W&G built some more fascinating stuff, which I videotaped.

Hi Dave, just watched that video on the plane. Loved every second of it but when you commented on the flathead screw "that's a bit rude" I laughed so hard🤣🤣. I have got one of these spm19. I will hook it up to a piece of wire and scan the band see what I get... Thanks for that great video and beautiful pictures.

I'm not German, but most of those things are more or less guessable for a Dutchman: Verstarker = amplifier (versterker in Dutch) Vorverstarker = preamplifier (voorversterker in Dutch) ZF-Verstarker = medium frequency amplifier (MF-versterker in Dutch) Umsetzer HF = high frequency converter (converter in Dutch, but "omzetter" literally translated gives converter) Gleichrichter = rectifier (gelijkrichter in Dutch) Frequenz teiler = frequency divider (frequentie deler in Dutch) Phasenjitterschaltung = phase and jitter circuit (phase en jitter schakeling in Dutch) Trager = carrier (drager in Dutch) Stufe = stage (trap in Dutch; the only German word in this video that looks more like English than Dutch) Btw, I always thought Rohde & Schwarz stood for skillful engineering, but this beast is on a higher level.

I have seen similar high spec equipment, and this one piece of equipment had like tiny pipes in it. After awhile of pulling it apart, I was like, perhaps I shouldn't be doing this in case it has chemicals in the pipes that shouldn't be released into the air. Turns out that my thinking is correct, as there was a great case overseas where people tried to strip something containing radioactive materials and spread it around the entire town.
