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.

The 40-756 is a high density RF multiplexer available in 50 Ω
and 75 Ω variants with up to 3xSP8T or 2xSP16T switches in a
single PXI module. It is available with three connector options;
SMB or SMA that provide a frequency range of 1.8 GHz (50 Ω)
/ 1.3 GHz (75 Ω), or multiway which limits the bandwidth to
1.3 GHz but offers a high density solution occupying one PXI
slot. The connectors used are fully supported by the range of
Pickering Interfaces connection solutions.
These modules offer low insertion loss and low VSWR
through the usable frequency range and each multiplexer has
been designed to have path independent loss.
The 40-756 is supplied with drivers that allow the user to
support the module in all popular PXI software environments.
In addition, the module can be supported in all Pickering’s LXI
Modular Chassis, allowing the use of a PXI or LAN controlled
switching solution with the same high levels of performance.
