Saving and Recalling States Using VISA and C

In this example, instrument settings are saved in the signal generator’s save register. These settings can then be recalled separately; either from the keyboard or from the signal generator’s front panel. Launch Microsoft Visual C++ 6.0, add the required files, and enter the following code into your .cpp source file. visaex8.cpp performs the following functions:

error checking

clears the signal generator

resets the status byte register

resets the signal generator

sets up the signal generator frequency, ALC off, power level, RF output on

checks for operation complete

saves to settings to instrument register number one

recalls information from register number one

prompts user input to put instrument into Local and checks for operation complete

The following program example is available on the signal generator Documentation CD- ROM as visaex8.cpp.

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

//PROGRAM FILE NAME:visaex8.cpp

//PROGRAM DESCRIPTION:In this example, instrument settings are saved in the signal

//generator's registers and then recalled.

//Instrument settings can be recalled from the keyboard or, when the signal generator

//is put into Local control, from the front panel.

//This program will initialize the signal generator for an instrument state, store the

//state to register #1. An *RST command will reset the signal generator and a *RCL

//command will return it to the stored state. Following this remote operation the user

//will be instructed to place the signal generator in Local mode.
