While I can always use a sig gen in the high MHz for my bench, I seem to do a lot with microphones/FFT/FHT, etc. lately. Do I need 2 separate meters, or can one get both types in a single box for ~$300 USD?TIA!
Specifically, has anyone come across a generator that can do all the normal kinds of "noise", or sweeping, or only outputting sweep/noise from/to specific frequencies? There are other things, like mixing a spike/harmonics with noise, overlapping or even adding signals, and I can see needing mixing (though I can do that with standard audio mixers I have).
Did you Google "audio signal generator" or "function generator"? I'd expect one with all the features you want to be expensive...Audacity can generate sine, square, and sawtooth waves that you can play with your soundcard. You'd have to write a program in Nyquist (a language used by Audacity) if you wanted a sweep or other wave shape. Or you can probably find an audio generator application, or an app for your phone. (But of course, the waveforms will be quantized and then filtered by the DAC so they won't be "perfect".)
What meters are you talking about?
