RIGOL Chapter 2 Command System
2-110 DG800 Programming Guide
Example
:SOUR1:PM 50 /*Sets the PM phase deviation of CH1 to 50°.*/
:SOUR1:PM? /*Queries the PM phase deviation of CH1 and the query returns 5.000000E+01.*/
[:SOURce[<n>]][:MOD]:PM:INTernal:FREQuency
Syntax
[:SOURce[<n>]][:MOD]:PM:INTernal:FREQuency {<frequency>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:PM:INTernal:FREQuency? [MINimum|MAXimum]
Description
Sets the PM modulation frequency of the specified channel.
Queries the PM modulation frequency of the specified channel.

Remarks
 This command is only applicable to the internal modulation source
(
[:SOURce[<n>]][:MOD]:PM:SOURce).
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns the PM modulation frequency in scientific notation, with 7 effective digits. For example,
1.500000E+02 (the PM modulation frequency is 150 Hz).
Example
:SOUR1:PM:INT:FREQ 150 /*Sets the PM modulation frequency of CH1 to 150 Hz.*/
:SOUR1:PM:INT:FREQ? /*Queries the PM modulation frequency of CH1 and the query returns
1.500000E+02.*/
[:SOURce[<n>]][:MOD]:PM:INTernal:FUNCtion
Syntax
[:SOURce[<n>]][:MOD]:PM:INTernal:FUNCtion {SINusoid|SQUare|TRIangle|RAMP|NRAMp|NOISe|USER}
[:SOURce[<n>]][:MOD]:PM:INTernal:FUNCtion?
Description
Sets the PM modulation waveform of the specified channel.
Queries the PM modulation waveform of the specified channel.

Remarks
 This command is only applicable to the internal modulation source
(
[:SOURce[<n>]][:MOD]:PM:SOURce).
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 SQUare: 50% duty cycle; TRIangle: 50% symmetry; RAMP: 100% symmetry; NRAMp: 0% symmetry;
USER: the arbitrary waveform selected for the specified channel.
