The following program example is available on the signal generator Documentation CD-ROM as
visaex11.cpp.
//************************************************************************
// PROGRAM FILE NAME: visaex11.cpp
//
// PROGRAM DESCRIPTION: This program sets up the signal generator to
// sweep from 1-2 GHz. A loop and counter are used to generate 5 sweeps.
// Each sweep consists of 101 points with a .01 second dwell at each point.
//
// The program uses a Sleep function to allow the signal generator to
// complete it's sweep operation before the INIT command is sent.
// The Sleep function is available with the windows.h header file which is
// included in the project.
//
// NOTE: Change the TCPIP0 address in the instOpenString declaration to
// match the IP address of your signal generator.
//
