I absolutely love the harmonious sounds they make when they're all spooled up! Glorious humming! An especially nice touch to see the wave forms while hearing them. Much thanks!
I wonder how many of these function generators were a part of a Hollywood sound studio; generating various futuristic science fiction sounds for both TV shows and movies.
The ground braking soundtrack to Forbidden Planet by Louis and Bebe Barron deserves a special mention ( ua-cam.com/video/aryHMPH7Kcc/v-deo.html ) . And also the BBC. They were an early creator of electronic music for their TV series.

I own the 3310A, and it’s my primary instrument in my musical outings. It’s one hell of an oscillator…put it through some effects…and it can sound like pretty much anything you like. I bought it on a goof, about 20 years ago, and will never get rid of it.
I bet! Even today getting a clean sine wave is pretty rare in synths. The whole video I was wondering how some of these would sound patched into a VCF and VCA and with enveloping…
Wonderful! I love analog synths and this was amazing. I was in high school in the mid 70's when synthesizers started to appear in popular music and I HAD to have one! The only way for me to afford one was to build one. Enter a company called PAiA. They sold synthesizer kits and not only did I get my first synth, but I learned how to solder and build electronic kits. Something I continue enjoy to this day. I still have my original Arp2600 that I bought used for $1200 in 1980.
Definitely sounds of old Dr Who in there. The funny thing was though that the sounds around 18:30 sound fairly like a hydraulic pump to me. Would be interesting to find an audio sample of a real one and compare it.
OMG I remember the 3310, it was standard in the lab I worked in. So easy to use, everything was obvious what it did. Im thinking you have created a Moog synthesizer :)
about halfway thru this video he starts messing about randomly playing with the connections and mentions VCO and i think to myself... where have i heard that before??? well in my DAW its still used as a construction element for modern synths even today. Then i realize he has now become one of those crazy synth people (but OG version). And sure enough! Very shortly after we are hearing some genuine and authentically generated 1960s scifi soundtrack. Well done! Actually i recently watched a relevant documentary about a famous early scifi film. Apparently they used a similar set of techniques? And it was one of the first ever instances of that? The Movie was called 'Forbidden Planet'. And we can find that documentary listed as 'Forbidden Planet Documentary' here on youtube. With those specific movie SFX part under discussion... that is located at +15 minutes timestamp onwards. If you want to skip directly to see that little piece of connected history.
A fun tour of these fantastic generators. I love your demonstration of the musical qualities of these lab instruments. Considering that dedicated keyboard and modular instruments were not available many years ago to create electronic music, early experimenters used lab gear to make their music :-) Fun stuff, thank you for so many hours of enjoyment watching your videos.
When I was a freshman Electrical Engineering student in 1988-89, I can remember messing around with one of those Model 3312 units in one of the labs. Obviously it was a hand-me-down from days past -- I'm sure they'd bought it new in 1975, and as time went on, they passed it down to lower level labs that weren't doing important research.
In the late 70s, I programmed an HP automated test rack controlling the instruments with HPIB. That HP3312 looks very familiar. In my off times I programed the two signal generators to play music (sort of).
I think another name for this episode could be Marc reinvents the radiophonics workshop. Some of the sounds there sound very like ones that terrified me behind the sofa in the 1970s watching dr who…
In the US, the emergency vehicle siren sounds are called "wail" for the low speed modulated tones, "yelp" for the medium speed and "hyper-yelp" for the high speed modulated tones. We also hear the two-tone sirens occasionally, similar to those heard outside the US.
Marc, you probably don’t monitor the comments on these older videos but if you do, I’d Like to hear your opinion on it. I need a signal generator for a project, and I see an HP 3312A on ebay for about 80$. Do you think that’s a good generator to get? Or should I look elsewhere.
I think every electronics lab, whether hobbyist, or professional, should have at least one or two analog function generators, power supplies, and oscilloscopes, very handy pieces of test-equipment, my old Dick Smith 20Mhz Dual-Trace Oscilloscope has an X/Y function that's handy for phase-measurements and testing of circuits.
Hi Marc, You seem to have found some crucial electronic tones. Good sounds. Have you heard the electonic music created by Bebe and Louis Barron music for 'The Forbidden Planet''' film. Interesting read and electric sounds. I think you found the Dr Who Dalek sound at 22:17-19 made in the famous BBC sound workshop. There was a couple of other sounds there that are famous from 60's 70's films.
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.
I have an ancient tube type wobbler which wobbles the frequency mechanically with a sliding capacitor mounted on a speaker voicecoil. Genius. Not made by HP, though.
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.
Great video, again. It is nice to see the evolution from what we call in Dutch a “toonfiets” (litterally signal/tone bicycle) to an arbitrary waveformgenerator. It’s important to remember where we came from.
I got a 3312A from a place I worked. It didn't function, turned out the freq pot had a broken solder joint. I changed it to a 10T pot and a vernier dial, a good machine.
Modern function generators are not as much fun as the old kit. I can remember hours of fun playing with them. Now you just punch in what you want and put pops out what you need.
I feel like you could make some money leasing your racks of equipment to movie production companies that are looking for props for sci-fi movies. Love the rack of 1960s stuff.
That Hainbach clip was pretty good, but honestly I bet you could do some music if you get a sequencer with control voltage output for your VCO input, some filters to mess around with on the output stage, and just a little bit of introductory music theory to let you pick chords to arpeggiate on the sequencer. You can just let them loop while you play with the sound, but you’ll at least get different tones rather than just one. Though I know a lot of people don’t want to take the time to trial and error like that. But I do say this because while talent is a factor, most of it can be learned. And you clearly have a good ear and you understand harmonics and stuff already - that’s a big head start honestly. It wouldn’t take much to focus that into musicality. A lot of historical musicians didn’t even start until they retired, after all! I loved the FM part especially - another layer or two of those complex overtones and that would be a wonderful FM pad to make chords and run through a chorus and reverb! So much depth and movement. I love FM.
this is how Delia Debyshire composed the original Doctor Who theme music from the very first original season. test equipment and reel-to-reel, no viable synths existed yet.
And I was thinking while watching the first part of the video: is he going to open it to find the cause of the slight asymetry...? Ah, there's going to be an entire companion video on it! Just on of the reasons why I love this channel! 😄
At the editing stage as we speak. We can't let a good repair of wayward vintage electronics go unpunished...

Yes, but can his interociter handle 1.21GW?
Several times during the course of this video, every dog in my neighborhood erupted in barking. Strange, that...

This is like watching people play with their eurorack synths, except we can actually see what's happening to the waveforms on the oscilloscope
Some (the best) Eurorack setups have tiny oscillators on the board :D

Great video as always.
Show the phase lock on the scope using x-y. That would be interesting, I guess: if you lock on an harmonic, you get a Lissajous picture.

Someone should let Hainbach know that your playing with old test equipment to make music.

Reminds me of early 1960s / 1970s Science-Fiction :D Love this Video :D
Yeah background sounds galore.
im going to make music with the HP 3300A, as a synth
Starting Saturday morning off right with the three C's: Coffee, cereal and CuriousMarc :)
"Comment below if you want--" Please.
This is reminds me so much of the 1960s rock band, Silver Apples. They used a bunch of really similar oscillators for their trippy music.
So when can we expect the wall of modular synths Marc? ;)
I've got that large HP function generator as well. When you open it up, the inside is a masterpiece of quality.
A baby Moog. The BBC Radiophonic Workshop.
These are both technical and musical instruments
I hear the original Dr. Who theme in that sine wave…
Love this HP equipment. Just gorgeous.
So these are the ancestors of my 33120A?

Now don't go too modern on us Marc! We have to get our fix of accurate tube driven test gear actually being used as intended, somewhere.

You should tease a new AGC episode but then make it about "automatic gain control" (as in audio compression/limiting.)
Yeah a fine oscillator but it had a custom IC which failed in my 3300. Drat.
