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.

40-755-x10 10 off SP4T RF MUX
Switching Diagram (Default Switch Paths Shown)
The 40-755 is a high density RF multiplexer available in
50 Ω and 75 Ω variants with up to 10xSP4T switches in
a single PXI module. It is available with two connector
options; SMB that provides 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.
40-755 RF Multiplexer Range:
10 off SP4T, 50 Ω, 1.8 GHz, SMB, Dual PXI Slot
10 off SP4T, 50 Ω, 1.3 GHz, Multiway, Single PXI Slot
5 off SP4T, 50 Ω, 1.3 GHz, Multiway, Single PXI Slot
4 off SP4T, 50 Ω, 1.8 GHz, SMB, Single PXI Slot
10 off SP4T, 75 Ω, 1.3 GHz, SMB, Dual PXI Slot
10 off SP4T, 75 Ω, 1.3 GHz, Multiway, Single PXI Slot
5 off SP4T, 75 Ω, 1.3 GHz, Multiway, Single PXI Slot
4 off SP4T, 75 Ω, 1.3 GHz, SMB, Single PXI Slot
The module offers low insertion loss and low VSWR through
its usable frequency range and each multiplexer has been
designed to have path independent loss.
The array of SP4T switches can be connected into alternative
configurations through the use of external cabling.
The 40-755 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.
