Generating a Swept Signal Using VISA and Visual C++
This example sets up the signal generator for a frequency sweep from 1 to 2 GHz with 101 points
and a .01 second dwell period for each point. A loop is used to generator 5 sweep operations. The
signal generator triggers each sweep with the :INIT command. There is a wait introduced in the loop
to allow the signal generator to complete all operations such as set up and retrace before the next
sweep is generated. visaex11.cpp performs the following functions:
• sets up the signal generator for a 1 to 2 GHz frequency sweep
• sets up the signal generator to have a dwell time of .01 seconds and 101 points in the sweep
• sleep function is used to allow the instrument to complete its sweep operation
The following program example is available on the signal generator Documentation CD- ROM as
visaex11.cpp.
