Step 3: Set Measurement Parameters
Measurement Trigger Parameters There are three measurement trigger parameters. They control the
arming of a measurement, the source of the trigger, and the trigger’s delay.
• The trigger arm parameter determines whether the test set makes one measurement and then stops
(single), or automatically re-arms upon completion of one measurement and repeats the process
(continuous). The recommended setting when writing a control program is single (CONTinuous OFF).
• The trigger source parameter selects the source of the measurement trigger signal. The recommended
Trigger Source setting when writing a control program is AUTO.
NOTE Trigger source is always IMMediate for analog measurements and cannot be changed by the user.
• The trigger delay parameter controls the delay between the trigger event (the point in time at which the
trigger signal is received) and the start of sampling. Negative values indicate that the sampling should
occur prior to the trigger event.
NOTE Trigger delay is not applicable to analog measurements.
NOTE You can set the Trigger Arm for all measurements to single (CONTinuous OFF) using the
following command syntax:
SETup[:ALL]:CONTinuous:OFF
Example 3. Programming Example:
OUTPUT Test_set;"SET:CONT:OFF"
sets the trigger arm to single for all measurements.
Example 4. Programming Example:
OUTPUT Test_set;"SET:DTXP:TRIG:SOUR AUTO"
sets the trigger source to AUTO for the digital transmit power measurement.
Example 5. Programming Example:
OUTPUT Test_set;"SET:DTXP:TRIG:DEL 10 US"
sets the trigger delay to 10 microseconds for the digital transmit power measurement.
