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.

40-870 Hex SPDT RF Switch Functional Diagram
(Default Switch Paths Shown)
The 40-870 is a 50 Ω RF Switch available with 3 or 6
separate SPDT relays in a single PXI slot.
The module has low insertion loss and VSWR through
the use of modern RF relay technology at an affordable
cost. The switch banks have excellent and repeatable RF
characteristics to 3 GHz with each path having a nominally
equal insertion loss. The 40-870 minimizes the injection of
noise and unwanted signals into the signal path by careful
attention to the mechanical and electrical design.
Versions with MCX or SMB connectors are available,
allowing users to simplify cabling issues by matching them
to other connectors in their test system.
The 40-870 is supplied with drivers that allow users
to support the module in all popular PXI software
environments. It can also be supported in all Pickering’s
LXI Modular Switching chassis, allowing the use of a PXI
or LAN controlled switching solution with the same high
levels of performance.
A 75 Ω version of the 40-870 is also available, the 40-830.
