WARNING
For versions with SMA connectors, only the correct connector series should be mated with these
modules. The 40/42-785C range uses SMA, SMA-2.9, SMA-2.4 & SMA1.85 connectors depending upon
the module’s frequency range, and the user should only mate the correct type to the module, failure to
do so may result in damage to the connector.
Also, it is important that the connector’s nut is properly tightened to the correct torque. For SMA
connectors, this should be with a 5/16 inch wrench and be 3-5 in·lbs (0.3 to 0.6 N·m) for brass, or 7-10
in·lbs (0.8–1.1 N·m) for stainless steel. For N-type connectors, this should be with an 18mm wrench and
be 15 in·lbs (1.7 N·m).

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.

pickering SECTION 1 - TECHNICAL SPECIFICATION
SECTION 1 - TECHNICAL SPECIFICATION
The 40-785C (PXI) and 42-785C (PXIe) range of PXI microwave
multiplexer modules are suitable for switching 50 Ω signals
up to 67 GHz. They are available in single or dual SP4T or
SP6T configurations with relays mounted on the front panel.
Remote versions are also available which can support up to
three multiplexers in a single slot.
The remote multiplexer versions, as well as occupying less
PXI panel space, allow the microwave relays to be placed
closer to the UUT and RF test equipment. This can shorten
the length of cables and improve system performance.
Remote versions are supplied with a 1.5 m interface cable.
The panel mounted 50 Ω terminated version occupies 3 slots
for the single version or 6 slots for the dual version. A 75 Ω
version is available with a bandwidth of 2.5 GHz and uses
Siemens 1.6/5.6 style connectors.

The 4x-785C range is suitable for constructing complex
microwave switching networks and includes configurations
to suit most applications. Connection is by high performance
SMA, SMA 2.9, SMA 2.4, SMA 1.85 or N-type for 50 Ω versions.
These modules give you the highest RF and microwave
performance available within a Pickering switching system.
Although designed for microwave applications, they have
many uses in the RF spectrum where extremely low insertion
loss and ultra high isolation are critical.
Product Compatibility
The 4x-785C range has been introduced as an update to the
existing 40-785B family. These remain orderable but the new
4x-785C is recommended as it provides additional options
such as the PXIe control interface. The RF performance of the
4x-785C is identical to the 40-785B.

4x-785C Terminated Multiplexer Range (triple versions are only available in remote mount format)
Relay Type
To provide maximum flexibility this range is available with either failsafe or
latching relays. For definition, the contacts of failsafe relays return to the
default state when the system power is removed whereas latching relay
contacts retain their last set state when the power is removed.
Relay Cycle Counting
To aid with module “health”
monitoring all versions are provided
with a relay cycle counting cycle
feature. The number of operations per
contact are stored on the module and
can be used to determine if a relay
is approaching EOL. This information
could allow system connections to
be revised so that signals applied to
heavily used contacts are swapped
with lightly used contacts to prolong
the working life of the relay(s). 4x-785C Unterminated Multiplexer Range (triple versions are only
