118 Keysight CXG, EXG, and MXG X-Series Signal Generators Programming Guide

Programming Examples

LAN Programming Interface Examples

ipromptf(id, "*IDN?\n", "%t", buf);// Query for id string

printf("Instrument ID: %s\n", buf);// Print id string to display

iclose(id);// Close the session

return 0;

}

VXI-11 Programming Using VISA and C++

The following program uses the VXI-11 protocol and the VISA library to control

the signal generator. The signal generator is set to a –5 dBm power level and

queried for its ID string. Before running this code, you must set up the interface

using the Keysight IO Libraries IO Config utility. vxivisa.cpp performs the

following functions:

— sets signal generator to a –5 dBm power level

— queries signal generator for an ID string

—error checking

The following program example is available on the signal generator

Documentation CD-ROM as vxivisa.cpp.

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

// PROGRAM FILE NAME:vxivisa.cpp

// Sample test program using the VISA libraries and the VXI-11

protocol

// NOTE: You must have the Keysight Libraries installed on your

computer to run

// this program

// PROGRAM DESCRIPTION:This example uses the VXI-11 protocol and

VISA to query

// the signal generator for its ID string. The ID string is then

printed to the

// screen. Next the signal generator is set for a -5 dBm power level

and then

// queried for the power level. The power level is printed to the

screen.

// IMPORTANT: Set up the LAN Client using the IO Config utility
