User Flatness Correction Downloads Using C++ and VISA

This sample program uses C++ and the VISA libraries to download user–flatness correction values to the signal generator. The program uses the LAN interface but can be adapted to use the GPIB interface by changing the address string in the program.

You must include header files and resource files for library functions needed to run this program. Refer to “Running C++ Programs” on page 59 for more information.

The FlatCal program asks the user to enter a number of frequency and amplitude pairs. Frequency and amplitude values are entered via the keyboard and displayed on the console interface. The values are then downloaded to the signal generator and stored to a file named flatCal_data. The file is then loaded into the signal generator’s memory catalog and corrections are turned on. The figure below shows the console interface and several frequency and amplitude values. Use the same format, shown in the figure below, for entering frequency and amplitude pairs (for example, 12ghz, 1.2db).

The program uses VISA library functions. The non–formatted viWrite VISA function is used to output data to the signal generator. Refer to the Agilent VISA User’s Manual available on Agilent’s website: http:\\www.agilent.com for more information on VISA functions.

The program listing for the FlatCal program is shown below. It is available on the CD–ROM in the programming examples section as flatcal.cpp.
