Chapter 3

Programming Examples

This chapter lists some programming examples in the development environments of
Visual  C++  6.0  and  Visual  Basic  6.0  and  LabVIEW  8.6  as  well  as  programming
example of how to control the analyzer to realize common functions in Linux operation
system. All examples are based on VISA (Virtual Instrument Software Architecture).

VISA is an API (Application Programming Interface) for controlling instruments. It is
convenient  for  users  to  develop  testing  applications  which  are  independent  of  the
types of instrument and interface. Note  the “VISA” mentioned here is NI (National
Instrument)-VISA. NI-VISA is an API written by NI based on VISA standards. You can
use NI-VISA to make a communication between the analyzer and the PC using USB or
such instrument bus. As VISA has defined a set of software commands, users can
control the instrument without understanding the working state of the interface bus.
For more details, please refer to NI-VISA.
