Programming Examples
Example 1)
20 ms pulse width, 2.3 ms delay, 10 Hz internal trigger, and continuous operation.
:PULSE1:STATE ON enables channel A
:PULSE1:POL NORM sets polarity to active high
:PULSE:WIDT 0.020 sets pulse width to 20 ms
:PULSE1:DELAY 0.0023 sets delay to 2.3 ms
:PULSE0:MODE NORM sets system mode to continuous
:PULSE0:PER 0.1 sets period to 100 ms (10 Hz)
:PULSE0:EXT:MODE DIS disables the external trigger
