printf("\n");

// Prints new line character to the display

getch();

 

 

viPrintf(vi, "POW:AMPL?\n");

//

Querys the power level

viScanf(vi, "%t", rdBuffer);

//

Reads the response into rdBuffer

//Prints the source power level

printf("Source power (dBm) is : %s\n", rdBuffer); printf("Press any key to continue\n");

viPrintf(vi, "FREQ:MODE?\n");

//

Querys the frequency mode

 

viScanf(vi, "%t", rdBuffer);

//

Reads the response into rdBuffer

//Prints the source freq mode

printf("Source frequency mode is : %s\n", rdBuffer); printf("Press any key to continue\n");

Generating a CW Signal Using VISA and C

This example uses VISA library functions to control the signal generator. The signal generator is set for a CW frequency of 500 kHz and a power level of −2.3 dBm. Launch

Microsoft Visual C++ 6.0, add the required files, and enter the code into your .cpp source file. visaex4.cpp performs the following functions:

verifies the GPIB connections and interface are functional

resets the signal generator

queries the instrument (CW frequency, power level, frequency mode, and RF state)

reads responses into the rdBuffer (CW frequency, power level, and frequency mode)
