SOUR1:PWM:INT:FREQ? MAX
+2.0000E+04
Returns the modulating frequency. (20kHz)
SOURce[1|2|3]:PWM:DUTY
Source Specific
Command
Description
Sets or queries the duty cycle deviation. The default
duty cycle is 50%.
Note
The duty cycle is limited by period, edge time and
minimum pulse width.
The duty cycle deviation of an external source is
controlled using the ±5V MOD INPUT terminal on
the rear panel. A positive signal (>0~+5V) will
increase the deviation (up to the set duty cycle
deviation), whilst a negative voltage will reduce
the deviation.
