:PM:DEViation

[SOURce]:PM:SENSitivity <value>

[SOURce]:PM: SENSitivity?

This command sets the phase modulation deviation. This setting will be used if :PM:SOURce is set to

LFGenerator.

The variable <value> is expressed in units of radians.

*RST 2.4048

:PM:SENSitivity

[SOURce]:FM:SENSitivity <value>

[SOURce]:FM: SENSitivity?

This command sets the phase modulation deviation per one volt peak amplitude signal input. This

setting will be used if :PM:SOURce is set to EXTernal.

The variable <value> is expressed in units of radians per Volt.

*RST 2.4048

:PM:INTernal:FREQuency

[SOURce]:PM:INTernal:FREQuency <value>

[SOURce]:PM:INTernal:FREQuency?

This command sets the phase modulation rate in Hz. This setting will be used if :PM:SOURce is set to

INTernal.

The variable <value> is expressed in Hertz.

*RST 400

:PM:INT:SHAPe

[SOURce]:PM:INT:SHAPe RD|RU|SINE|SQUare|TRIangle

[SOURce]:PM:INT:SHAPe?

This command specifies the PM modulation shape. RD selects Ramp-Down and RU ramp up.

Standard waveforms available are SINE, SQUare and TRIangle.
