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)
frequency 1000 Hz (sets the frequency to 1000 Hz)
pulse:delay 50 ns (sets the delay to 50 ns)
volt:low +100V (sets the DC voltage to +100V, and thus I
F
≈ +100 mA)
volt -20V (sets the pulse voltage to -20V, and thus I
R
≈ -100 mA)
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 on (turns on the output)
pulse:delay 50 ns (sets the delay to 50 ns)
volt:low +100V (sets the DC voltage to +100V, and thus I
F
≈ +100 mA)
volt -20V (sets the pulse voltage to -20V, and thus I
R
≈ -100 mA)
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)
pulse:delay 50 ns (sets the delay to 50 ns)
volt:low +100V (sets the DC voltage to +100V, and thus I
F
≈ +100 mA)
volt -20V (sets the pulse voltage to -20V, and thus I
R
≈ -100 mA)
output on (turns on the output)
These commands will satisfy 90% of your programming needs.
