ESA/PSA Programming Examples

Using C and Service Request (SRQ) to

Determine When a Measurement is Complete

This C programming example (SRQ.c) can be found on the

Documentation CD.

/*************************************************************************

* SRQ.C

* Determine when a measurement is done by waiting for SRQ

* and reading Status Register

* Instrument Requirements:

* PSA/ESA/EMC Series Spectrum Analyzers.

* This C programming demonstrates how:

* A. Set the service request mask to assert SRQ when

* either a measurement is uncalibrated or an error

* message has occurred.

* B. Initiate a sweep and wait for the SRQ interupt

* C. Poll all instruments and report the nature of the

* interrupt on the spectrum analyzer

* You have a royalty-free right to use, modify, reproduce and distribute

* the Sample Application Files (and/or any modified version) in any way

* you find useful, provided that you agree that Agilent Technologies has

* no warranty, obligations or liability for any Sample Application Files.

* Agilent Technologies provides programming examples for illustration only,

* This sample program assumes that you are familiar with the programming

* language being demonstrated and the tools used to create and debug

* procedures. Agilent Technologies support engineers can help explain the

* functionality of Agilent Technologies software components and associated

* commands, but they will not modify these samples to provide added

* functionality or construct procedures to meet your specific needs.
