I'm interested in the frequency spectrum of the voltage output of a vibration sensor (Kemet VS-BV203-B) at frequencies up to about 100 kHz (so either the fft or a timeseries). Unfortunately I don't have the budget for very expensive loggers/analyzers and was wondering if anyone has any suggestions in how to obtain this for a budget below say 750?
The vibration sensor has three wires, power at 3.3V, GND and signal output, which is biased by half the power voltage. I though perhaps an audio recorder may work? Are there any oscilloscopes or spectral analyzers for that budget that work too?
