Running the trigger model
You can run the trigger model when the instrument is controlled either locally or remotely. If the
instrument is being controlled locally, you can quickly configure the trigger model without setting up
trigger source and trigger count in the trigger layer. Trigger source is set to immediate triggering and
trigger count is set to 1.
To set up trigger model from the front panel:
1. Press the Menu Key.
2. Under Trigger, highlight the Configure icon and press ENTER. The trigger configure screen is
displayed.
3. Select the button next to Idle. Press the ENTER key to enable the continuous initiation.
With continuous initiation enabled (INIT:CONT ON), the instrument continuously performs
measurements. With continuous initiation disabled (INIT:CONT OFF), the instrument returns to the
idle state after all measurements are complete (based on the product of arm count, trigger count and
sample count). When the instrument is in the idle state, pressing the TRIGGER key initiates the
trigger model.
4. Select the button next to Arm Source and press ENTER. The arm source selection screen is
displayed.
You can select immediate, external, and manual triggering from the front panel. Bus triggering is only
supported using SCPI commands. You can also quickly set up the arm source by pressing HOME >
Acquire. If you set the arm source to External, digital I/O line 1 is forced to be Trigger In and is used
as the external source. For details, refer to Digital I/O (on page 3-19).
5. Select the button next to Sample Count and press ENTER. The sample count editing screen is
displayed. The maximum sample count is 2500.
