Discriminator Measurement using FM Rate and Deviation Calibration
Making the
Measurement
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 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.
