Configuring Trigger Attributes In Local Mode - Tektronix KEITHLEY System SourceMeter 2636B Reference Manual

Series 2600B System SourceMeter® Instrument Reference Manual
The following figure shows the general sequence for measurement triggering. The basic sequence is:
•
When the output is turned on, the programmed source value is immediately applied to the device
under test (DUT).
•
Through front panel only: If the immediate trigger source is selected, a measurement is triggered
immediately. However, if the manual trigger source is selected, the 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 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 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.
INTERVAL: Sets the time interval between measurements (0 s to 999.999 s) when the count is
greater than 1.
DELAY: Sets the delay period between the trigger and the start of measurement (0 s to 999.999 s).
