Disable or enable PWM. To avoid multiple waveform changes, you can
enable PWM after you have set up the other modulation parameters. The
default is OFF. The :PWM[1|2]:STAT? query returns “0” (OFF) or “1”
(ON). The instrument will allow only one modulation mode to be enabled at
a time. For example, you cannot enable PWM and AM at the same time.
When you enable PWM, the previous modulation mode is turned off. The
instrument will not allow PWM to be enabled at the same time that sweep
or burst is enabled. When you enable PWM, the sweep or burst mode is
turned off. PWM is allowed only when pulse is the selected function.
