L4421A Datasheet, PDF (3/9 Pages) Keysight Technologies – 40-Channel Armature Multiplexer

System connections
you can trust
The L4421A comes with 2 heavy duty
50-pin Dsub connectors that allow for
simple, reliable connections. Each con-
nector uses 30 micro-inches of gold to
ensure a repeatable, accurate measure-
ment. Other connection options include:
–– Detachable terminal blocks with
strain relief
–– Low-cost, standard 50-pin Dsub
connector kits and cables
–– Mass interconnect solutions
Ethernet connectivity enables
simple connection to the
network and remote access
to measurements
The Ethernet interface offers high-
speed connections that allow for
remote access and control. You can
set up a private network to filter out
unwanted LAN traffic and speed up the
I/O throughput, or take advantage of
the remote capabilities and distribute
your tests worldwide. Monitor, trou-
bleshoot, or debug your application
remotely. Ethernet communication also
can be used with the support of LAN
sockets connections.
The optional GPIB interface has many
years of proven reliability and can be
used for easy integration into existing
applications. The L4421A ships with
the Keysight E2094N I/O Libraries
Suite making it easy for you to config-
ure and integrate instruments into
your system — even if your system
includes instruments from multiple
vendors.
Figure 2. The web interface makes it easy to set up, troubleshoot and maintain
your test remotely.
Fully-featured graphical web
interface makes it easy to
set-up and troubleshoot your
tests from anywhere in the
world
The built-in web interface provides
remote access and control of the
instrument via a Java-enabled browser
such as Internet Explorer. Using the
web interface, you can set up, trouble-
shoot, and monitor your instrument
from remote locations.
–– View and modify instrument setup
–– Open or close switches
–– Send, receive and view
–– SCPI commands
–– Define and execute switch sequences
–– View error queue
–– Get status reports on relay counts,
firmware revisions, and more
Additionally, since the web interface is
built into the instrument, you can
access it from any operating system
that supports the web browser without
having to install any special software.
Password protection and LAN lockout
are also provided to limit access for
additional security.
Software for most popular
programming environments
Full support for standard programming
environments ensures compatibility
and efficiency. You can use direct I/O
with the software you already have, or
use standard IVI and LabVIEW software
drivers that provide compatibility with
the most popular programming
environments:
–– Keysight VEE Pro
–– National Instruments LabVIEW, Lab-
Windows/CVI, TestStand, and
Switch Manager
–– Microsoft C/C++ and Visual Basic
