Triggering 10-13
C) For the first pass through the model, the scanner does not wait at point B. Instead, it
closes the first channel (point C).
D) After the relay settles, the Model 7001/2 outputs a trigger pulse. Since the instrument is
programmed to scan 10 channels, operation loops back to point B, where it waits for an input
trigger.
E) and F) With the SourceMeter operation at point A, the output trigger pulse from the
Model 7001/2 triggers a measurement of DUT #1 (point E). After the measurement is com-
plete, the SourceMeter outputs a trigger pulse and then loops back to point A, where it waits for
another input trigger.
The trigger applied to the Model 7001/2 from the SourceMeter closes the next channel in the
scan, which then triggers the SourceMeter to measure that DUT. This process continues until
all 10 channels are scanned and measured.
Con fi guring triggering
Triggering is configured from the CONFIGURE TRIGGER menu and is structured as
follows.
NOTE See “Trigger model” for details on the following programmable aspects of
triggering.
CONFIGURE TRIGGER menu
Press CONFIG and then TRIG to display the menu shown below and in Figure 10-8. (Note
that bullets indicate the primary items of the menu, while dashes and slashes indicate options.
See Section 1,
Rules to navigate menus to check and/or 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.
