Section 8: Triggering
Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual
Remote trigger example
summarizes the command sequence for basic trigger operation. These commands set
up Model 6482 triggering as follows:
•
Arm layer source: Bus
•
Arm layer count: 2
•
Trigger layer delay: 0.1 s
•
Trigger layer count: 10
•
Trigger layer output events: Source and sense
•
Trigger layer trigger link output line: 1
After the instrument is set up, :INIT is sent to take the instrument out of the idle state. *TRG is sent
to trigger the instrument, after which it cycles 10 times through the trigger layer. A second *TRG is
required to trigger the instrument the second time, and it then completes the second cycle through
the trigger layer.
NOTE
You must allow sufficient time between the first and second *TRG commands, or the
second trigger will be ignored.
