Since I've been cranking away on projects, I decided to rearrange things on the bench a bit to make it easier to use my test equipment.
I went from this mess:
To this mess:
I've been using my oscilloscope a lot on these audio projects, and this new stack also lets me integrate a new acquisition into the mix.
The newest instrument is in the second level, on the right side. It's an HP 8904A Multifunction Synthesizer. This will be used as an external modulation source for my HP 8657B RF Signal Generator, specifically for generating the FM Stereo Multiplex Composite Waveform (whew! whatta mouthful!) so I can do a complete alignment on an FM Broadcast receiver.
The old Heathkit IG-37 that I have that basically got me back to the bench Big Time is meant to do this, but I'm not really happy with how well it works. It's a 1950's design, is really touchy to get properly aligned, and has a reputation for having a high distortion level. Thew new HP will generate a very clean, very stable waveform that will modulate the RF generator. This instrument can also produce Sine, Square, Ramp, and Triangle waveforms, and will allow you to mix them, sum them, or modulate each other. It's very close to being an "Arbitrary Waveform Generator", but not as complex.
The shop/lab/dungeon is still cluttered and messy, but I'm slowly making progress on getting it organized into a proper work area. That cardboard honeycomb core door has to go, as it doesn't give me enough workspace for equipment, tools, and Unit Under Repair. I'd like to get some countertops, and make U-Shaped workbench, but I still have to come up with a frame to hold the new work surface.
Oh, well.....It Keeps Me Out Of Bars At Night!
