Queries for GPIB Using VISA and C
This example uses VISA library functions to query different instrument states
and conditions. Launch Microsoft Visual C++ 6.0, add the required files, and
enter the following code into your .cpp source file. visaex3.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)
— turns signal generator RF state off
— verifies RF state off
The following program example is available on the signal generator
Documentation CD-ROM as visaex3.cpp.
