Triggering in local mode
It is not necessary to change any trigger settings to use the basic source and measurement
procedures covered in this section.
Press the
MENU
key, and then select
SETUP > RECALL > INTERNAL > FACTORY
to reset the
factory default conditions.
The following figure shows the general sequence for measurement triggering. The basic sequence is
as follows:
•
When the output is turned on, the programmed source value is immediately applied to the device
under test (DUT).
•
Through virtual front panel only: If the immediate trigger source is selected, a measurement is
triggered immediately. However, if the manual trigger source is selected, the virtual front-panel
TRIG key must be pressed.
•
The instrument waits for the programmed delay period (if any).
•
The instrument takes one measurement.
•
If the number of measurements is less than the programmed trigger count, it cycles back to take
another measurement (the measurement cycle will be repeated indefinitely if the infinite trigger
count is selected).
•
For multiple measurements, the instrument waits for the programmed trigger interval (if any)
before taking the next measurement.

Configuring trigger attributes in local mode
From the virtual front panel, press the
CONFIG
key, and then select
TRIG
. The following menu items
are shown:
TRIGGER-IN:
Use these options to select the trigger-in source:
•
IMMEDIATE
: Triggering occurs immediately and the instrument starts to make measurements
when it is ready (for example, after the source output is turned on).
•
MANUAL
: The virtual front-panel TRIG key must be pressed to trigger the instrument to take
readings.
COUNT:
Sets the trigger count (number of measurements) as follows:
•
FINITE
: The instrument goes through measurement cycles for the programmed trigger count (1 to
99999).
•
INFINITE
: The instrument goes through measurement cycles indefinitely until halted.
