Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 8: Triggering
• TRIG-LAYER : Use this menu item to configure the trigger layer of the trigger model:
– TRIGGER-IN : Use to select the detection event for the trigger layer:
- IMMEDIATE : Event detection occurs immediately.
- TRIGGER-LINK : After selecting this trigger-in source, you will be prompted in
sequence as follows:
> TRIG-IN TLINK LINE: Select the input line (#1, #2, #3, #4, #5, or #6) for the trigger
link.
> EVENT-DETECT-BYPASS: Set the bypass for the Source Event Detector. With
ONCE, operation will loop around the Source Event Detector. With NEVER
selected, operation will wait for an input trigger.
> TRIGGER-IN-EVENTS: Enable (ON) or disable (OFF) trigger-in events
(SOURCE, DELAY, and MEAS). With a trigger-in event ON, operation will wait at
that event for an input trigger. With the trigger-in event OFF, operation will not
wait; it will continue and perform the appropriate action.
– TRIGGER OUT : Use to configure the trigger layer output trigger:
- LINE : Select the trigger link line for the output trigger; line #1, #2, #3, #4, #5, or #6.
- EVENTS : Enable (ON) or disable (OFF) output triggers that occur after the
SOURCE, DELAY, and MEAS actions.
– DELAY : Specify the time delay (in seconds) for the trigger delay.
– COUNT : Specify the trigger count.
• HALT : Use to return the Model 6482 to the idle state. HALT does not turn off the output. The
programmed source level will still be available at the OUTPUT terminals. The following
actions will take the Model 6482 out of an idle state:
– Turn the output off and then on again.
– Reselect the arm or trigger event.
– Exit from the menu structure, and then reenter it by pressing CONFIG and then TRIG.
