Discriminator Measurement using FM Rate and Deviation Calibration

1. press the Continue key when you are ready to make the measurement.

Calibrating the Measurement

The calibration procedure determines the discriminator constant to use in the

transfer response by measuring the system response to a known FM signal.

Note that the system must be operating in quadrature during calibration.

2. First establish quadrature by adjusting the phase shifter until the meter

indicates 0 volts, then press Continue.
