DMM7510-901-01 Rev. B / May 2015
The event can be any of the events described in the following table.
Event
Description
Digital Input
Line edge detected on a digital input line. When you select this
option, you will also select the digital input to monitor.
After selecting the digital input line, press
Config
to select the type
of edge (falling, rising, or either).
TSP-Link Input
Line edge detected on a TSP-Link synchronization line. When you
select this option, you will also select the TSP-Link line to monitor.
After selecting the TSP-Link line, press
Config
to select the type of
edge (falling, rising, or either).
Timer
A trigger timer expired. When you select this option, you will also
select the timer to monitor.
After selecting the timer, press
Config
to select the delay time,
count, or start time.
Command
A command interface trigger (bus trigger):
•
Any remote interface: *
TRG
•
GPIB only: GET bus command
•
VXI-11: VXI-11 command
device_trigger
Display TRIGGER
Key
Front-panel TRIGGER key press.
External In Trigger
Use a pulse from the external I/O. When you select this option,
press
Config
to select the type of edge (falling, rising, or either).
Analog Trigger
Use the analog trigger.
LAN In Trigger
A LXI trigger packet is received on LAN trigger object. When you
select this option, you will also select the LAN trigger to monitor.
After you select the line, press
Config
to select the type of edge
(falling, rising, or either).
Blender
Wait for the events set by an event blender.
None
No trigger event. The trigger model will not run if the wait event is
set to none.
If you need to set up the trigger model to wait for an event under some conditions but not others, you
can use a branch block. For information, see
Action blocks
The action blocks start an action in the instrument, such as making a measurement or clearing a
buffer.
Measure block
When trigger model execution reaches the block:
1. The instrument begins making a measurement.
2. The trigger model execution waits for the measurement to complete.
3. The instrument places the measurement into the specified reading buffer, which cannot be of the
writable buffer style.
If you are defining a user-defined reading buffer, you must create it before you define this block.
When you set the count to a finite value, trigger model execution remains at the block until all
measurements are complete. If you set the count to infinite, the trigger model executes subsequent
blocks and measurements continue in the background until the trigger model execution reaches
another measure block, a wait block, or until the trigger model ends.
