[:SOURce<hw>]:PM:MODE <Mode>

Selects the mode for the phase modulation.

Parameters:
<Mode>
HDEViation | HBANdwidth | LNOise
HDEViation

Provides full setting range of PhiM deviation. The range of modulation frequency is limited (see data sheet). Recommended for low modulation frequencies and/or high PhiM deviation.

HBANdwidth

Provides maximum range of modulation bandwidth. Recommended for high modulation frequencies.

LNOise

Provides modulation with phase noise and spurious characteristics close to CW mode. The range for modulation bandwidth and PhiM deviation is limited (see data sheet)

*RST:HBANdwidth
Example: PM:MODE LNO

selects Low Noise mode for external phase modulation.

Options: Option R&S SMA-B20 or R&S SMA-B22
Manual operation: See "ɸM Mode"
