[SOURce:]PM:STATe ON|OFF|1|0 OFF
:PM:DEViation
[SOURce]:PM:SENSitivity
[SOURce]:PM: SENSitivity?
This command sets the phase modulation deviation. This setting will be used if :PM:SOURce is set to
LFGenerator.
The variable is expressed in units of radians.
*RST 2.4048
:PM:SENSitivity
[SOURce]:FM:SENSitivity
[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 is expressed in units of radians per Volt.
*RST 2.4048
:PM:INTernal:FREQuency
[SOURce]:PM:INTernal:FREQuency
[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 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.
