Interface Check Using VISA and C

This program uses VISA library functions to communicate with the signal generator. The program verifies that the RS- 232 connections and interface are functional. In this example the COM2 port is used. The serial port is referred to in the VISA library as ‘ASRL1’ or ‘ASRL2’ depending on the computer serial port you are using. Launch Microsoft Visual C++, add the required files, and enter the following code into the .cpp source file. rs232ex1.cpp performs the following functions:

•prompts the user to set the power on the signal generator to 0 dBm

•error checking

•resets the signal generator to power level of –135 dBm

The following program example is available on the signal generator Documentation CD- ROM as rs232ex1.cpp.

PROGRAM NAME:

rs232ex1.cpp

//

 

 

//PROGRAM DESCRIPTION: This code example uses the RS-232 serial interface to

//control the signal generator.

//

//Connect the computer to the signal generator using an RS-232 serial cable.

//The user is asked to set the signal generator for a 0 dBm power level

//A reset command *RST is sent to the signal generator via the RS-232

//interface and the power level will reset to the -135 dBm level.The default

//attributes e.g. 9600 baud, no parity, 8 data bits,1 stop bit are used.

//These attributes can be changed using VISA functions.

//

//IMPORTANT: Set the signal generator BAUD rate to 9600 for this test //****************************************************************************************
