[:SOURce]:FM:FREQuency?

Description

Set the FM modulation frequency.
Query the FM modulation frequency.

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, for example,

20000. In addition, <value> can also be set in "Number + Unit" form, for

example, 20kHz.

 The default unit of the return value is Hz.

 After the modulation frequency is set, you can use the up/down direction keys

or knob to modify the modulation frequency at the current step. You can query

or set the current step using the

[:SOURce]:FM:FREQuency:STEP[:INCRement]

command.

 When selecting "Ext" modulation source, this operation is invalid.

Return Format

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

Example

:FM:FREQ 20kHz
:FM:FREQ?

1kHz

Explanation

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

5000. In addition, <value> can also be set in "Number + Unit" form, for

example, 5kHz.

 The default unit of the return value is Hz.

 After the modulation frequency step is set, 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 modulation frequency using the

[:SOURce]:FM:FREQuency

command.

Return Format

The query returns the FM modulation frequency step, for example, 5000.

Example

:FM:FREQ:STEP 5kHz
