[:SOURce]:PULM:INTernal[1]:PWIDth <num>[<time suffix>]|UP|DOWN
[:SOURce]:PULM:INTernal[1]:PWIDth?
This command sets the pulse width for the internally generated pulse modulation
source.
The optional variable [<time suffix>] accepts nS (nano-seconds) to S (seconds).

Key Entry
Pulse Width
Remarks If the entered value for the pulse width is equal to or greater than the
value for the pulse period, the pulse width will change to a value that
is less than the pulse period.
Refer to “:PULM:INTernal[1]:PWIDth:STEP” for setting the value
associated with the UP and DOWN choices.
