How to Generate a FLuctuating Voltage
How to Generate a FLuctuating Voltage
(OP)
Is there a device on the market that I can use to create a modulating voltage at low currents (100-500mA). I want to do this first on a bench, then from a DC voltage source.
I don't know the V-range, or the frequency I need. That will be determined from bench testing.
My initial thought was a "black box" already exists that will accomplish this for me. Is this correct, or will I need to design a circuit to create this output?

You need an input signal for the amplifier. The obvious choice is a programmable arbitrary generator. But you can use anything that delivers a low level signal that does what you want. There are freeware signal generator programs on the web. You can then generate the signal in your computer and use the earphone output to couple it to the amplifier. Possibilities are countless.

I keep a one channelized stereo amp on the shelf for just such abuse.
