PROGRAMMING YOUR PULSE GENERATOR
KEY PROGRAMMING COMMANDS
The “Programming Manual for -B Instruments” describes in detail how to connect the
pulse generator to your computer, and the programming commands themselves. A
large number of commands are available; however, normally you will only need a few of
these. Here is a basic sample sequence of commands that might be sent to the
instrument after power-up:
*rst (resets the instrument)
trigger:source internal (selects internal triggering)
output:load 500 (Tells the instrument that you are using a 500Ω load. This
affects the duty cycle limit.)
output:impedance 0 (sets the output impedance to 0Ω. The only other allowed
setting is output:impedance 50.)
frequency 1000 Hz (sets the frequency to 1000 Hz)
pulse:width 1 us (sets the pulse width to 1 us)
pulse:delay 2 us (sets the delay to 2 us)
volt 200 (sets the amplitude to 200 V)
output on (turns on the output)
For triggering a single event, this sequence would be more appropriate:
*rst (resets the instrument)
trigger:source hold (turns off all triggering)
output:load 500 (Tells the instrument that you are using a 500Ω load. This
affects the duty cycle limit.)
output:impedance 0 (sets the output impedance to 0Ω. The only other allowed
setting is output:impedance 50.)
pulse:width 1 us (sets the pulse width to 1 us)
pulse:delay 2 us (sets the delay to 2 us)
output on (turns on the output)
volt 200 (sets the amplitude to 200 V)
trigger:source immediate (generates a single non-repetitive trigger event)
trigger:source hold
(turns off all triggering)
output off (turns off the output)
To set the instrument to trigger from an external TTL signal applied to the rear-panel
TRIG connector, use:
*rst (resets the instrument)
trigger:source external (selects internal triggering)
output:load 500 (Tells the instrument that you are using a 500Ω load. This
affects the duty cycle limit.)
