Programming Examples

Example 1)

20 ms pulse width, 2.3 ms delay, 10 Hz internal trigger, and continuous operation.

:PULSE1:STATE ON <cr> <lf>

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:TRIG:MODE DIS <cr> <lf>

disables the external trigger

To start the pulses use either of the following commands:

:PULSE0:STATE ON <cr> <lf>

starts the pulses

:INST:STATE ON <cr> <lf>

alternate form to start pulses

Example 2)

25μs pulse width, 0 delay, external trigger, and one pulse for every trigger.

:PULSE1:STATE ON <cr> <lf>

enables channel A

:PULSE1:POL NORM <cr> <lf>

sets polarity to active high

:PULSE:WIDT 0.000025 <cr> <lf>

sets pulse width to 25

:PULSE1:DELAY 0 <cr> <lf>

sets delay to 0
