Sample Program - Agilent Technologies 4288A Programming Manual

Starting (Triggering) Measurement and Waiting for Completion of Measurement
Waiting For Completion Of Measurement (detecting completion of
measurement)

Sample program

Example 5-1 shows a sample program to detect the completion of measurement using an
SRQ. This program is stored on the sample program disk under the filename
"srq_meas.bas."
This program stops the trigger system, sets up SRQ, and then starts up the trigger system
once. When an SRQ of the completion of the measurement occurs, it displays a
"Measurement Complete" message and finishes.
The program is detailed below.
