The Amplitude Modulator is a device for precisely modulating a signal's amplitude. This is done by using a multiplying circuit. Inputs are differential voltage sensing, and single ended current sensing. This fulfills single ended input signal requirement and gives ground loop isolation.
All inputs have times one and times ten scale for signal to noise optimization.
Both an 'in phase' and an '180 degree out of phase' 50ohm output are featured. The output has a 1.0 times and 0.1 times switch for signal to noise optimization. Two summed modulating inputs are available, each with a 180 degree phase switch. A 'calibrated in percent' zero-modulation carrier control.
