Section 8: Triggering Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual
Configuring triggering
Triggering is configured from the CONFIGURE TRIGGER menu. This menu is structured as
follows.
NOTE See Front-panel operation of the trigger model , for details on the programmable aspects
of triggering.
CONFIGURE TRIGGER menu
Press the CONFIG key and then the TRIG key to display the menu shown below and in Figure 8-
8 . Note that bullets indicate the primary menu items; dashes and slashes indicate available
options and attributes. See Section 1 , “Rules to navigate menus,” to check and change trigger
options.
• ARM-LAYER : Use this menu item to configure the arm layer of the trigger model:
– ARM-IN : Use to select the detection event for the arm layer:
- IMMEDIATE : Event detection occurs immediately.
- MANUAL : Event detection occurs when the TRG key is pressed.
- GPIB : Event detection occurs when a bus trigger (GET or *TRG) is received.
- TIMER : Initially, event detection is satisfied immediately. Subsequent event
detection occurs after the timer interval elapses. After selecting this arm event, you
will be prompted to specify the timer interval (in seconds).
- MANUAL : Event detection occurs when the TRIG key is pressed.
- TLINK : After selecting this arm event, you will be prompted to select the input line
for the trigger link and the state of the event detection bypass. With ONCE selected,
operation will loop around the arm event detector on each new pass through the
trigger model. With NEVER selected, operation always waits for the input trigger.
-
↓
STEST : Event detection occurs when the start of test (SOT) line of the OUTPUT
ENABLE connector is pulsed low. After selecting this arm event, you will be
prompted to select the state of the event detection bypass. With ONCE selected,
operation will loop around the arm event detector on each new pass through the
trigger model. With NEVER selected, operation always waits for the input trigger.
-
↑
STEST : Event detection occurs when the SOT line of the OUTPUT ENABLE
connector is pulsed high. After selecting this arm event, you will be prompted to
select the state of the event detection bypass.
-
↑↓
STEST : Event detection occurs when the SOT line of the OUTPUT ENABLE
connector is pulsed either high or low. After selecting this arm event, you will be
prompted to select the state of the event detection bypass.
– ARM OUT : Use to configure the arm 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) the arm layer output triggers.
TRIG-LAYER-DONE ON enables an output trigger when the trigger layer is exited.
– COUNT : Specify the arm count, FINITE (programmable count) or INFINITE (non-stopping
count).
