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.

40-729 8x4 Matrix With
Optional Loop-Thru
40-727/728/729 are RF matrix modules suitable for
switching frequencies up to 300 MHz. They are available in
50 Ω or 75 Ω versions front panel SMB coaxial connectors.
The modules provide a simple and scalable bidirectional
matrix for RF frequencies and are intended for the easy
construction of high performance matrix switching
systems.
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 40-727/8/9 are high density matrices designed to
provide a Y to X connection to maximize bandwidth. They
can also support limited X to X connectivity as shown in
the manual.
These modules are 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 with a
minimum loss of bandwidth.
Supported by eBIRST
50Ω SMB versions without loop-thru are supported
by eBIRST switching system test tools. These simplify
switching system fault-finding by quickly testing the
system and graphically identifying the faulty relay.
