1 About the Instrument
This manual contains component, configuration, and programming information
for the Keysight L4490A/L4491A RF Switch Platform.
The L4490A and L4491A control and monitor RF/microwave switches and
attenuators used in applications such as wireless communications, avionics,
medical electronics, and in test and measurement systems. The L4490A and
L4491A are optimized for use with the Keysight family of RF/microwave switches
and attenuators.
The L4490A is a 2U, and the L4491A is a 4U LXI Class C instrument. LXI, an
acronym for LAN eXtensions for Instrumentation is an instrumentation standard
for devices that use the Ethernet (LAN) as their primary communication interface.
The 2U and 4U references refer to the physical size of the L4490A and L4491A
relative to standard EIA rack cabinet dimensions.
