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.

anti-static bags.

CAUTION - PRODUCT DOCUMENTATION SYMBOL

and understood before attempting to install or operate the product.

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.

interface cables

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
