Making music with test equipment has been the core of electronic music for a lot of the early electronic music era. The original Doctor Who Theme is another example of test equipment making music. The ingenuity of some people and thinking outside the square can really make for amazing breakthroughs. Thanks for another trip down memory lane while giving this equipment a new lease on life.

About the phase lock with adjustable phase -- Before the availability of modern Bode analyzers, I participated one whole week end doing Lissajous patterns. We (my boss and I) analyzed a tube and thyratron based speed control system performance, or actually lack of it. We had two rented instruments, a scope with slow decay yellow trace and a two-output phase shift oscillator. The process involved sending one channel signal through the control loop. The process output was on the scope Y-axis. The phase shifted second channel went to the scope X-axis. The Y axis indicated the loop gain and by adjusting the phase shift to match, i.e. to minimize the Lissajous loop, we could read the controller phase shift from the dial. The measurements at various frequencies produced our Bode diagram. I plotted the data on a log-log chart. That was tedious, but still workable way. And it was the first time I had even heard about the workings of the Bode diagram. But we got the necessary information for considerably improving our (purchased) controller stability. It also served us to a few months later replace the original system with our own design, a new SCR control.

I found this looking for stuff on the 3312A. I was working on trying to test a stepper motor driver, asked a friend at the college i work at for some help. Loaned me a 3312A, tried didn't work he helped me said i was right, grabed another worked but was had touchy knobs. He grabbed some newer one tried got my thing going. Finished he said take those two HPs maybe you can make one work fro mthe two, then came back with a 3rd i guess he figured was also junk but worked, fixed the scratchy one, junked the DOA one for some donor parts for the one i repaired. I had to mess with positioning the potentometer for the frequency though once repaired. I got it fairly acurate, but low (1-100HZ) frequencies are off.

What killed my 3312 was just the pushbutton switches. Put some Deoxit over them and it rejuvenated it. These pushbuttons are notorious for oxidizing, so I wouldn’t be surprised if most of them had the problem by now. Each range has its own calibration I think, you have to look at the service manual and find the right one to tweak.

Useful indeed! I've been quite happy with the Wavetek 193 I have; got it quite some years ago, when I was still in high school, I think for $120 used on eBay. Even faster than (and, about as functional as, by the look of it?) the HP 3312, it boasts a whopping 20MHz range! Though it doesn't have variable symmetry on the full range, that's only available on a ÷10 setting. The design is quite complex, taking advantage of a handful of fast ECL (MC10k family) to handle the state, and the usual CCS-into-capacitor design for timing. Indeed the Wavetek in Hainbach's clip is, if not a 190 family (it's not the 193 exactly, maybe a 191?), then certainly a contemporary of them. :) The one drawback is, the fast (TO-39) power transistors in the output stage are hard to find, and prone to failure; IIRC, I blew them just from driving a bipolar transistor, the poor thing can't handle a 50% shorted load apparently, how embarrassing? I replaced the quad of those, with a pair of much beefier, but not nearly as fast, 2SA/2SC family complements; the frequency response rolls off significantly past a few MHz and the peppy 10ns risetime is gone, but the functions are still as handy as ever. Well, that and programmability; as I'm very slowly, just beginning to automate aspects of my system (e.g. scope and spec accessible via GPIB-serial adapter), the 100% manual interface makes repetitive testing somewhat less attractive. Perhaps I'll get an arb gen one of these days; or some wired DMMs, or... :)
