[:SOURce]:ILS[:GS|GSLope]:DDM:POLarity <Polarity>
The command enters the polarity for DDM calculation (see
The DDM depth calculation depends on the selected polarity:
- Polarity 90 Hz - 150 Hz (default setting):
DDM = [ AM(90 Hz) - AM (150 Hz) ] / 100% - Polarity 150 Hz - 90 Hz:
DDM = [ AM(150 Hz) - AM (90 Hz) ] / 100%
