[:SOURce[<n>]][:MOD]:PWM:INTernal:FREQuency
Syntax [:SOURce[<n>]][:MOD]:PWM:INTernal:FREQuency
{<frequency>|MINimum|MAXimum}
[:SOURce[<n>]][:MOD]:PWM:INTernal:FREQuency? [MINimum|MAXimum]
Description Set the PWM modulation frequency of the specified channel.
Query the PWM modulation frequency of the specified channel.
Parameter Name Type Range Default
[<n>] Discrete 1|2 1
<frequency> Real 2mHz to 1MHz 100Hz
Explanation  This command is only applicable to the internal modulation source
( [:SOURce[<n>]][:MOD]:PWM:SOURce ).
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related
parameters of CH1 by default.
Return Format The query returns the PWM modulation frequency in scientific notation with 7
effective digits, for example, 1.500000E+02 (the PWM modulation frequency is
150Hz).
Example :SOUR1:PWM:INT:FREQ 150 /*Set the PWM modulation frequency of CH1 to
150Hz*/
:SOUR1:PWM:INT:FREQ? /*Query the PWM modulation frequency of CH1 and
the query returns 1.500000E+02*/
