enables channel A
:PULSE1:POL NORM <cr> <lf>
sets polarity to active high
:PULSE:WIDT 0.020 <cr> <lf>
sets pulse width to 20 ms
:PULSE1:DELAY 0.0023 <cr> <lf>
sets delay to 2.3 ms
:PULSE0:MODE NORM <cr> <lf>
sets system mode to continuous
:PULSE0:PER 0.1 <cr> <lf>
sets period to 100 ms (10 Hz)
:PULSE0:EXT:MODE DIS <cr> <lf>
