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.

40/42-724-021-L
32x8 Matrix With
Loop-Thru
The 40-724 (PXI) and 42-724 (PXIe) are RF matrix modules
suitable for switching frequencies up to 300 MHz. Having a
50 Ω characteristic impedance and front panel SMB
connectors, these modules provide a simple and scalable
bidirectional matrix for RF and are intended for the easy
construction of high performance switching systems.
The 40/42-724-021-L version includes Y loop-thru connectors
to allow easy matrix expansion between adjacent modules.
All X and Y connections have isolation switches. These can be
used to disconnect the matrix from the external test fixture to
maximize isolation and RF performance.
Matrix Operation
The 40/42-724 is a high density matrix designed to provide a
Y to X connection to maximize bandwidth.
This module is based on the same construction as the
popular 40-725 RF matrix, but has increased capacity and
optional Y axis loop thru allowing easy expansion.
Supported by eBIRST
This module is supported by eBIRST test tools. These
simplify switching fault-finding by quickly testing the
system and graphically identifying the faulty relay.

Overview
96x8 RF Matrix Created from 2-off 40/42-724-021-L and 1-off 40/42-724-021
(Loop-thru cables interconnect the Y-buses of each 32x8 matrix module)
Y Axis Loop-Thru
The easy to use loop-thru option allows 40/42-724 modules to be cascaded to form larger matrices whilst
minimizing impact on RF performance.
The 40/42-724-021-L version of the module has Y loop-thru connectors on the front panel which are simply
plugged into the Y connectors of the adjacent matrix module via SMB to SMB coaxial cables.
The loop thru system is designed to provide an extended connection from Y to X.
The inter-module front panel wiring for an example 96x8 matrix is shown below and the switching diagram is
show overleaf.
