Chapter 7 Programming Overview
The T3VNA Series analyzer features LAN and USB Device interfaces. By using a computer with
these interfaces, and a suitable programming language (and/or NI-VISA software), users can remotely
control the analyzer based on SCPI (Standard Commands for Programmable instruments) command
set, LabView and IVI (Interchangeable Virtual Instrument), to interoperate with other programmable
instruments.
This chapter introduces how to build communication between the analyzer and a controller computer
with these interfaces.
