Chapter 4 Programming Demos
This chapter provides the demos for programming and controlling the power supply using SCPI commands
under Excel, Matlab, LabVIEW, Visual Basic and Visual C++ environment on the basis of NI-VISA.
NI-VISA (National Instrument-Virtual Instrument Software Architecture) is an advanced application
programming interface developed by NI (National Instrument) for communicating with various instrument
buses. It can communicate with instrument in the same method regardless of the type of the instrument
interface (GPIB, USB, LAN/Ethernet or RS232).
The instruments communicate with NI-VISA via various interfaces are called “resources”. The VISA
descriptor (namely the resource name) is used to describe the accurate name and location of the VISA
resource. If LAN interface is currently used for communicating with the instrument, the VISA descriptor
is :TCPIP0::172.16.2.13::INSTR. Before programming, please acquire the correct VISA descriptor.
