NOTE: Amplitude default of −10 dBm is typically sufficient for performing
measurements on passive cavities, however higher levels may be needed to
measure the cavity notch depth. The level can be changed to suit measurement
needs (e.g. increase measurement range, minimize incident input from other
sources, etc.). If Amplitude is changed, Ref Level will also have to be
changed.
