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.

SECTION 1 - TECHNICAL SPECIFICATION
The 40-727A/728A/729A (PXI) and 42-727A/728A/729A
(PXIe) are high density RF matrix modules suitable for
switching up to 300 MHz in 50 Ω or 100 MHz in 75 Ω. They
are available in 50 Ω or 75 Ω versions with SMB connectors
or in 50 Ω versions with a multiway connector. They provide
a simple and scalable bidirectional matrix for RF signals
and are intended for the construction of high performance
switching systems. All X and Y connections have isolation
switches. These can be used to disconnect the matrix from
the test fixture to maximize isolation and RF performance.
Updated Product
These modules are based on the established 40-727/8/9. As
well as having PXIe options, they use Pickering reed relays
throughout giving improved operation speed and reliability.

SECTION 1 - TECHNICAL SPECIFICATION
Matrix Operation
The 4x-727A/728A/729A are designed for X
to Y connections with maximum bandwidth.
They can also support X to X connections in
the same module or between multiple
modules (using loop-thru option) - see user
manual.
They are based on the same architecture
as the popular 40-725 RF matrix, but have
optional Y loop-thru allowing
easy expansion with minimum loss of
bandwidth.
