[:SOURce]:PM:FREQuency:STEP[:INCRement]
Syntax [:SOURce]:PM:FREQuency:STEP[:INCRement] <value>
[:SOURce]:PM:FREQuency:STEP[:INCRement]?
Description Set the modulation frequency step of ØM.
Query the modulation frequency step of ØM.

Default
<value> Real 1Hz to 50kHz 1kHz
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, 5kHz.
 After the modulation frequency step is set, you can rotate the knob to modify
the modulation frequency at the current step. At this point, you can query or set
the modulation frequency using the [:SOURce]:PM:FREQuency command.
Return Format The query returns the modulation frequency step of ØM. For example, 5.00000kHz.
Example
:PM:FREQ:STEP 5kHz
:PM:FREQ:STEP?

Discrete
EXTernal|INTernal
INTernal
Explanation  EXTernal: select "Ext" modulation source. At this point, the external modulating
signal is input from the [EXT MOD IN] connector.
 INTernal: select "Int" modulation source. At this point, the instrument provides
the modulating signal and you can set the modulation frequency and
modulation waveform of the modulating signal.
Return Format The query returns the ØM modulation source. For example, INT.
