We are looking for a solution that can help us to plot a frequency response of an amplifier or a filter.
We are using sweep generator that drives the UUT and in the output we connect a RF detector that translates the freq to voltage (low freq video) signal.
The generator has a ramp signal that represents the 1freq sweep that we can use as a referense signal.
The freq. BW of the system will be app. 50MHz.
Please recommend your best choise.
