Reading the Data Questionable Status Register Using VISA and C
In this example, the signal generator’s data questionable status register is
read. You will be asked to set up the signal generator for error generating
conditions. The data questionable status register will be read and the program
will notify the user of the error condition that the setup caused. Follow the user
prompts presented when the program runs. Launch Microsoft Visual C++ 6.0,
add the required files, and enter the following code into your .cpp source file.
visaex9.cpp performs the following functions:
