[:SOURce]:PM:FREQuency

Syntax

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

Description

Set the modulation frequency of ØM.
Query the modulation frequency of ØM.

Default

<value>

Real

100mHz to 1MHz (Sine)

100mHz to 20kHz (Square)

10kHz

Explanation

 When <value> is set in "Number" form, the default unit is Hz. Besides,

<value> can also be set in "Number + Unit" form, for example, 20kHz.

 The default unit of the return value is Hz.

 After setting the modulation frequency, you can use the up/down direction

keys or knob to modify the modulation frequency at the current step. At this

point, you can query or set the current step using the

[:SOURce]:PM:FREQuency:STEP[:INCRement]

command.

 This command is invalid when the ØM modulation source is set to "Ext".

Return Format

The query returns the ØM modulation frequency, for example, 20000.

Example

:PM:FREQ 20kHz
:PM:FREQ?
