Hi,
im looking to use a spectrum analyzer for creating some frequency response plots. the circuit i am looking to measure is a voltage controlled oscillator. I know that (from measurement) that voltages from 1.0V to 1.2V will generate about 50Hz to about 65Hz.
My concern is that my input control voltage range is too small (0.2V), and im not sure how large of a perturbation signal i should be inputting from my network analyzer. does anyone have any suggestions or comments if this will work? any tricks on how i can increase this range without have to do any major design changes?
