Appendix A — Example
A-1 C/C++
This example is run on the command line. It sends the *IDN? query to the instrument and
prints the response to the console.
// IdnExample.cpp : Microsoft Visual Studio-Generated Example
// Based on Example 2-1 in the NI-VISA User Manual
// Usage : IdnExample "TCPIP::xxx.xxx.xxx.xxx::inst0::INSTR"
// where xxx.xxx.xxx.xxx is the IP address of the
// instrument.
// Output : The string identity string returned from the
// instrument.
// VISA Header : visa.h (must be included)
// VISA Library : visa32.lib (must be linked with)
