SAT Deviation

The SAT Deviation measurement is multiplexed on the same field with the FM Deviation measurement. When the CALL CONTROL screen is selected, SAT Deviation will be displayed automatically. To select SAT Deviation on the other screens listed below, select FM Demod in the AF Anl In field, position the cursor next to FM Deviation, and press the knob to display a list of choices. Choose SAT Deviation from this list.

GPIB Example

“DISP ACNT;MEASure:AFRequency:SATDeviation?“

displays the CALL CONTROL screen and queries the SAT Deviation measurement.

Operating Considerations

The SAT Deviation measurement will always return a measurement result, regardless of whether or not a signal is input to the Test Set. This measurement is performed using a digital signal processing algorithm, and if the value returned is extremely large it is simply measuring noise.

The SAT Deviation measurement does not require any external test equipment for calibration.
