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

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.

SECTION 1 - TECHNICAL SPECIFICATION
The 40-780B (PXI) and 42-780B (PXIe) Microwave switching
modules consist of one, two, three or four SPDT switches
capable of switching frequencies to 67 GHz in 50 Ω or 2.5 GHz
in 75 Ω. Connections are made via front panel mounted high
quality RF coaxial connectors, SMA/N-Type for 50 Ω and
1.6/5.6 in 75 Ω versions. Remote versions are also available
which can support up to three SPDT relays in a single slot.
The remote versions, as well as occupying less panel space in
the case of the triple options, 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 multiplexers are supplied with a 1.5 m interface cable.
The 4x-780B range gives you the highest RF and microwave
switching 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. They may
also be used for lower frequency RF applications where power
handling to 240 W is required (700 W for N-Type options).
Product Compatibility
The 4x-780B range has been introduced as an update to the
existing 40-780A family. These remain orderable but the new
4x-780B is recommended as it provides additional options
such as the PXIe control interface. The RF performance of the
4x-780B is identical to the 40-780A.

SECTION 1 - TECHNICAL SPECIFICATION
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).
