WARNING - Hazardous Environments Symbol

This product is not speciﬁcally designed for use in hazardous environments, for example in explosive

atmospheres. If the product is to be used in hazardous environments we recommend that the user ensures

suitable protective measures are taken.

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:

• 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.

• 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.

• Outer clothing worn must be unable to generate static charges.

• Printed Circuit Boards (PCBs) ﬁtted with these devices must be stored and transported in anti-static bags.

Warnings & Cautions

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 PXI/PXIe/LXI 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 - Product Documentation Symbol

Suitably qualiﬁed & trained users should ensure that the accompanying documentation is fully read 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.

Section 1 - Technical Speciﬁcation

The 40-782B (PXI) and 42-782B (PXIe) have one or two

microwave transfer switches with a characteristic impedance

of 50 Ω and are available in 18 GHz, 26.5 GHz, 40 GHz or 50 GHz

versions. Connections are made via front panel mounted high

quality SMA, SMA 2.9 or SMA 2.4 coaxial connectors, depending

upon the frequency range.

Transfer switches have four ports with two switch states. In

the default (de-energized) state, ports 1 to 2 and 3 to 4 have

signal paths between them. In the energized state the signal

paths are between ports 1 to 3 and 2 to 4 (see diagrams).

The 4x-782B gives you the highest RF and microwave

switching performance available within a Pickering switching

system. Although designed for microwave applications, they

(Part No. 4x-782B) in Single Format

have many uses in the RF spectrum where extremely low

insertion loss and ultra high isolation are critical. They may

also be used for lower frequency applications where power

handling to 240 W is required.

Remote Versions

The remote versions, as well as occupying less panel space,

allow the microwave transfer switches to be placed closer to

the UUT and RF test equipment. This can shorten the length of

cables and improve system performance. Remote switches are

supplied with a 1.5 m interface cable.

PXI/PXIe Microwave Transfer Switch Modules

Issue 4.0 September 2022

Page 1.2 pickeringtest.com

Section 1 - Technical Speciﬁcation

Product Compatibility

The 4x-782B range has been introduced as an update to the

existing 40-782A family. The existing family remains orderable but

the new 4x-782B is recommended as it provides additional options

such as the PXIe control interface. The RF performance of the

4x-782B is identical to the existing 40-782A.

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).
