[:SOURce]:AM:FREQuency
Syntax [:SOURce]:AM:FREQuency <value>
[:SOURce]:AM:FREQuency?
Description Set the AM modulation frequency.
Query the AM modulation frequency.

Default
<value> Real
10Hz to 100kHz (Sine)/10Hz 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.
 After the modulation frequency is set, you can rotate the knob to modify the
modulation frequency at the current step. You can set and query the current
step using the
[:SOURce]:AM:FREQuency:STEP[:INCRement] command.
 When the modulation source of AM is set to "Ext", this command is invalid.
Return Format The query returns the AM modulation frequency. For example, 20.00000kHz.
Example
:AM:FREQ 20kHz
:AM:FREQ?

Default
<value> Real 1Hz to 50kHz 1kHz
Explanation  When <value> is set in "Number" form, the default unit is Hz. In addition,
<value> can also be set in "Number + Unit" form; for example, 3.55kHz.
 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]:AM:FREQuency command.
Return Format The query returns the AM modulation frequency step. For example, 3.55000kHz.
Example
:AM:FREQ:STEP 3.55kHz
:AM:FREQ:STEP?
