Getting Started
a common standard for software developers so that software from multiple
vendors, such as instrument drivers, can run on the same platform. TekVISA
is industry-compliant software, available with selected Tektronix instruments.
You can use this software to write (or draw) interoperable instrument drivers in
a variety of Application Development Environments (ADEs). It implements
a subset of Version 2.2 of the VISA specification for controlling GPIB and
serial (RS-232) instrument interfaces locally or remotely via an Ethernet LAN
connection.
Installation
Use an internet browser to access the Tektronix Web site (www.tektronix.com)
and download the current TekVISA to your PC. Unzip the downloaded file in a
temporary directory of your choice and run Setup.exe.
NOTE. The details on TekVISA concepts and operations are explained in the
TekVISA Programmer Manual that can be also found on the Tektronix Web site.
