Front panel triggering
To control triggering from the front panel, press CONFIG followed by TRIG, then set up trigger
parameters as described below:
TRIGGER-IN — Use these options to select the trigger-in source:
• IMMEDIATE: Triggering occurs immediately and the unit starts once it is ready to take
measurements (for example, after the source output is turned on).
• MANUAL: The 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 unit will cycle through measurement cycles for the programmed trigger count
(1 to 99999).
• INFINITE: The unit will cycle through measurement cycles indefinitely until halted.
INTERVAL — Sets the time interval between measurements (0s to 999.999s) when the COUNT is
greater than 1.
DELAY — Sets the delay period between the trigger and the start of measurement (0s to
999.999s).
Front panel triggering example
As an example, assume you wish to set up triggering as follows:
• Manual triggering (TRIG key)
• Infinite trigger count (cycle indefinitely through measurement cycles)
• Interval (time between measurements): 1s
• Delay (time from trigger to measurement): 2s
Set up this example as follows:
1. Press CONFIG then TRIG.
2. Select TRIGGER-IN, then press ENTER or the navigation wheel.
3. Select MANUAL, then press ENTER or the navigation wheel.
4. Choose COUNT, then select INFINITE, and press ENTER or the navigation wheel.
5. Select INTERVAL, set the interval to 1s, then press ENTER or the navigation wheel.
