Saving ASCII Trace Data in an ASCII File

This is the C programming example TraceASC.c /*************************************************************************** *TraceASC.c

*Agilent Technologies 2001

*

*E4406A VSA Series Transmitter Tester using VISA for I/O *This Program shows how to get and save an ASCII trace *The C program does the following:

*Open session to GPIB device at address 18 *Check opening session success

*Set the instrument to Basic Mode *Reset device

*Set the input port to the internal 50MHz reference source *Zoom the spectrum display

*Tune the analyzer to 50MHz

*Set the analyzer in single mode

*Trigger a spectrum measurement and wait for it to complete *Query the spectrum trace information

*Save the info trace to buffer *Query the spectrum trace data

*Save the spectrum trace data to buffer *Set the analyzer back to continuous mode *Save trace data to an ASCII file *Close session
