Front-panel operation of the trigger model
The flow chart in
summarizes triggering for front-panel operation. The trigger model is
modeled after the remote commands used to control triggering (refer to
). Key
trigger model settings are included in The flow chart graphically illustrates front-panel operation of
the trigger model. Note that the BENCH defaults are denoted by the “
+
” symbol.
The primary actions of the trigger model are source, delay, and measure. The source action
outputs the programmed voltage bias value, and the programmed delay provides a settling period
for the voltage bias source before the measurement is performed.
The trigger model consists of two layers (arm layer and trigger layer) to provide versatility.
Programmable counters allow operations to be repeated, and various input and output trigger
options are available to provide source-measure synchronization between the Model 6482 and
other instruments using the trigger link.
Unless noted, the programmable aspects of the trigger model are performed from the
CONFIGURE TRIGGER menu. See
“Configuring triggering,” page Section 8-12
NOTE
The trigger model and associated settings and commands affect both channels
simultaneously.
Idle
The Model 6482 is in idle mode when it is not operating in the arm layer or trigger layer of the
trigger model. When in idle mode, the ARM indicator is off. To take the Model 6482 out of idle
mode, turn the output ON.
The Model 6482 can be returned to an idle mode state at any time by selecting the HALT menu
item of the CONFIGURE TRIGGER menu. See
