Generating an Externally Applied AC-Coupled FM Signal Using VISA

and C

In this example, the VISA library is used to generate an ac-coupled FM signal

at a carrier frequency of 700 MHz, a power level of −2.5 dBm, and a deviation

of 20 kHz. Before running the program:

— Connect the output of a modulating signal source to the signal generator’s

EXT 2 input connector.

— Set the modulation signal source for the desired FM characteristics.

Launch Microsoft Visual C++ 6.0, add the required files, and enter the code into

your .cpp source file. visaex5.cpp performs the following functions:

—error checking

— resets the signal generator

— sets up the EXT 2 connector on the signal generator for FM

— sets up FM path 2 coupling to AC

— sets up FM path 2 deviation to 20 kHz

— sets carrier frequency to 700 MHz

— sets the power level to -2.5 dBm

— turns on frequency modulation and RF output

The following program example is available on the signal generator

Documentation CD-ROM as visaex5.cpp.

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

// PROGRAM FILE NAME:visaex5.cpp

// PROGRAM DESCRIPTION:This example sets the signal generator FM

source to External 2,

// coupling to AC, deviation to 20 kHZ, carrier frequency to 700 MHz

and the power level

// to -2.5 dBm. The RF state is set to on.
