Keysight PXI Multiplexer and Matrix Switch Modules Introduction
The multiplexer modules deliver high-speed signal routing to a single point and
are ideal for routing multiple analog signals to a measurement device in
automated test environments (ATE) or data acquisition systems.
The matrix switch modules deliver medium to high density switching of multiple
channels on a single module. Connect any row to any column — ideal for routing
multiple signals between the device under test and instruments.
Keysight also supplies software drivers that allow you to support the modules in
all popular PXI chassis’ and programming environments. Soft Front Panel
software allows you to exercise the channels for test purposes.
Keysight AgMSwitch driver version 1.1.x or later or the Keysight
LabVIEW G driver version 1.1.x or later is required for
programmatic control of these switch modules.
These modules are not for connection to Mains.

Step 1: Unpack and Inspect the Module
Keysight’s PXI switch modules are shipped in materials that
prevent static electricity damage. The modules should only be
removed from the packaging in an anti-static area ensuring that
correct anti-static precautions are taken. Store all modules in
anti-static envelopes when not in use.
Step 1: Unpack and Inspect the Module
ESD
Electrostatic discharge (ESD) can damage or destroy electronic components. All
work on electronic assemblies should be performed at a static-safe work station.
The following figure shows an example of a static-safe work station using two
types of ESD protection.
-Conductive table-mat and wrist-strap combination.
-Conductive floor-mat and heel-strap combination.
Both types, when used together,
provide a significant level of ESD
protection. Of the two, only the
table-mat and wrist-strap
combination provides adequate ESD
protection when used alone. To
ensure user safety, the static-safe
accessories must provide at least 1
M of isolation from ground.
Purchase acceptable ESD
accessories from your local supplier.

-PXI hardware does not support “hot-swap” capabilities
(changing modules while power is applied to the chassis).
-Before installing or removing Keysight PXI Modules, the chassis
must be powered off to prevent damage to the PXI module.
Remove all cables/terminal blocks from the module prior to
installing or removing the module.
These modules can be used in a chassis with a cPCI, PXI-1, or
PXIh chassis peripheral slot.
The modules can be installed in any standard PXI slot
marked with a peripheral slot compatibility image (a
circle containing the slot number).
The modules can also be installed in any hybrid PXI
slot marked with a peripheral slot compatibility image
(the letter “H” and a solid circle containing the slot
number).
1 Make sure the PXI chassis power is turned off.
2 If the chassis has multiple fan speed settings, ensure that the fans are set to
automatic. Do not set the fan speed to low or turn them off.
3 Position the chassis with ample space between the chassis fan intake and
exhaust vents. Blockage by walls or obstructions affects the air flow needed
for cooling. (Refer to the chassis documentation for cooling information).
4 The modules are shipped with thread protectors over the mounting screws.
These must be removed before installing the modules in a chassis.
5 Holding the PXI module by the injector/ejector handle, slide it into an

9 If you are using a remote controller, connect the System Interface Card in the
chassis to the host computer.
10 Plug in and power up the PXI chassis. Verify that the chassis fans are
operating and free of obstructions that may restrict airflow.
If you are using a remote controller linked to the M9021A Cable
Interface, you must Shut Down the PC BEFORE you power down
the chassis. When you restore power, you must power up the
chassis BEFORE you power up the PC.
If you are using MXI-3 to connect a desktop PC to a PXI chassis or
link to multiple chassis, power up the system as follows:
- For a system with a PC and one chassis, power up the chassis
before powering the PC.
- For a system with more than one chassis, power on the last
chassis in the system followed by the penultimate, etc. Finally,
turn on the PC or chassis containing the system controller.
11 If you are using a remote host computer (rack mount, desktop, or laptop PC),
power-on the computer. Choose the default option for any “Found New
Hardware” dialogs.
After all of the “Found New Hard ware” dialogs are complete, you

channel 36 and the isolation relay closed.
Beginning with SFP Version 1.1.x, if you have another application, either your own
program or another instance of the SFP interface, that has initialized the switch
module, then the SFP enters it’s “monitor” mode. In this mode, you cannot change
relay state and the menu buttons are grayed-out. However, as the other
application controls the channels, the SFP interface monitors and displays the
state of the individual relays. Refer to the SFP help file for additional information.
Verify operation
There are no specific operational verification or self test procedures. However, you
can use the Soft Front Panel software to open and close individual channels.
Module specifications are guaranteed by design.

Characteristics
For detailed module characteristics and specifications, refer to the module Data
Sheet on the Switch ModuleSoftware and Product Information CD or the Switch
data sheet online at www.keysight.com/find/pxiswitch.
Default Path Settings
The table below lists the default or power down state for the matrix and
multiplexer modules. This default switch path is also shown in the following
diagrams.
Switch modules are considered a “wear-out” item. It is normal for
relay performance to degrade over time; life expectancy depends
on the specific application and use model. Hot-switching of relays
decreases useful life more rapidly than no-load switching. Refer
to the product data sheet for approximate lifetimes under
different loads. Premature wear-out due to application
requirements and damage due to accidental over-current or
over-voltage conditions are not covered by product warranty.

Electrical Operating Conditions
To avoid electric shock, Turn off the chassis and disconnect
or de-energize all field wiring to the modules before
installing or removing any module or chassis slot cover.
Transients
The multiplexer and matrix modules described in this manual are designed to
safely withstand occasional transient voltages up to 1500 Vpeak. Typically, these
transient over voltages result from switching inductive loads or from nearby
lighting strikes.
Not for connection to mains. Do not connect any of the
modules d irectly to a mains power outlet. If it is necessary
to switch a large ind uctive load, you must add signal
conditioning elements to reduce the potential transients
before they reach the modules.
Electrical Operating Conditions
High Energy Sources
These modules are designed to handle inputs up to their rated currents or their
rated powers, whichever is less. Under certain fault conditions, high energy
sources could provide substantially more current or power than a module can
handle. It is important to provide external current limiting, such as fuses, if the
module inputs are connected to high energy sources.
For the latest specifications, check the Keysight web site at:
www.keysight.com/find/pxiswitch.
Install current limiting devices between high energy sources and
the module inputs.

Environmental Operating Conditions
These modules are designed to operate in a temperature range of 0 °C to +55 °C
with non-condensing humidity. The maximum humidity is 95% at 40
use in locations where conductive dust or electrolytic salt dust may be present.
These modules should be operated in an indoor environment where temperature
and humidity are controlled. Condensation can pose a potential shock hazard.
Condensation can occur when the modules are moved from a cold to a warm
environment, or if the temperature and/or humidity of the environment changes
quickly.
These modules are not for connection to Mains.
Refer to the data sheet for maximum voltage, current, and power dissipation
ratings for each module. If conditions change, ensure that condensation has
evaporated and the modules have thermally stabilized until Pollution Degree 1
