WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
atmospheres. If the product is to be used in hazardous environments we recommend that the user
ensures suitable protective measures are taken.
!
WARNING - DANGER OF ELECTRIC SHOCK SYMBOL
This module may contain hazardous voltages. Before removing the module from the rack remove all
supplies and disconnect user I/O signals.
Unused slots in the host chassis are populated with blanking plates to prevent access to user
I/O signals that may be present. Blanking panels are available to order from Pickering in a variety
of slot widths. If the product is not used in this manner for example by using an extender card then
additional care must be taken to avoid contact with exposed signals.
CAUTION - HANDLING OF ELECTROSTATIC-SENSITIVE DEVICES SYMBOL
Certain semiconductor devices used in this equipment are liable to damage due to static voltage.
Observe the following precautions when handling these devices in their unterminated state, or
sub-assemblies containing these devices:
1. Persons removing sub-assemblies from equipment using these devices must be earthed by a
wrist strap and a resistor at the point provided on the equipment.
2. Soldering irons used during the repair operations must be low voltage types with earthed tips and
isolated from the mains voltage by a double insulated transformer.
3. Outer clothing worn must be unable to generate static charges.
4.
anti-static bags.
CAUTION - PRODUCT DOCUMENTATION SYMBOL
and understood before attempting to install or operate the product.

SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS
All cleaning and servicing requires the equipment to be isolated and disconnected from the power source and user I/O
signals (refer to the Maintenance Section).
• Appropriate manual handling procedures should be followed as dictated by the weight of the individual module or
the combined weight of the modules & chassis.
• Should a fault occur with the module or chassis, immediately isolate and disconnect the incoming power to the
chassis and the user I/O signals.
• Ensure the equipment is installed, operated and maintained by trained and authorised personnel.
• For suitably equipped products in the event of an emergency press the red “emergency stop” button situated on
the front of the unit.

PXI 6 U Expandable 250 MHz 16x16 RF Matrix 45-720A
ISSUE 7.1 APR 2020
y16x16 Coaxial Matrix
y250 MHz Bandwidth
yHigh Quality Ruthenium Reed Relays
yChoice of Front Panel Mounted Coaxial Connectors
yAvailable in 50 Ω and 75 Ω Versions
yUses High Reliability Reed Relays
yVISA/IVI Drivers Supplied for Windows
y3 Year Warranty
The 45-720A module is a 6 U 16x16 RF Matrix suitable for
switching frequencies beyond 250 MHz. It is available in
50 Ω and 75 Ω versions with a choice of coaxial connectors.
It is intended for the easy construction of high performance
bi-directional matrix switching systems.
Automatic isolation switches are located on all input and
output connections. These are used to disconnect unused
signals from the external test fixture to maximize isolation
and RF performance.
Typical applications are switching signals to high speed
digitizers. The matrix is constructed using high reliability
ruthenium electro-plated reed relays, with an operational
life of >108 to give maximum switching confidence with long
service and stable contact resistance.
Matrix Operation
The 45-720A is a true 16x16 high density
matrix, any combination of cross-points
may be selected. Only the signal is
switched, all grounds are common. Loop-
thru is included on X signals.
Easy Expansion with Automatic Loop-Thru
All unused X input channels are
automatically switched to the
corresponding “Loop-thru” output
connection. This allows for simple
expansion (with a little performance loss)
and permits the user to place matched
terminations on the outputs if required.

Matrix Expansion
Larger matrices may be constructed by daisy-chaining the X signals from multiple modules, for example, six modules form a 96x16
matrix (1536 crosspoints). Expansion is achieved by interconnecting Xout (Loop-thru) of one matrix to Xin of the next using coaxial
cables as shown below. It should be noted that the operating bandwidth will reduce slightly as the number of modules is increased.

Matrix Modules Can be Daisy-Chained to
