Installing the Keysight IO Libraries
The Keysight IO Libraries include the VISA and VISA-COM libraries used for 
programming the 53220A/53230A in Microsoft® development environments 
(Table 2-1). The VISA and VISA-COM libraries allow you to send commands from 
the 53220A/53230A SCPI command set to the instrument. The IO libraries also 
include Keysight Connection Expert described and used later in this chapter.
The IO Libraries are contained on the Keysight Automation-Ready CD or may be 
downloaded from the Electronic Test & Measurement Software page at:
http://www.keysight.com
Before installing the IO libraries, review Table 2-2 to verify that your computer 
meets the specifications required for the latest version of the software. 
The Keysight IO Libraries (VISA and VISA-COM) must be installed prior to 
installing any other I/O drivers (e.g. IVI-C, IVI-COM).
The Keysight IO Libraries and utilities are often updated to include additional 
features and improve usability. The figures used in this chapter represent the 
latest version of the IO Libraries available at the time of printing. While you may 
have a different version, the process of configuring and adding instruments to an 
interface remains basically the same.
