WARNINGS AND CAUTIONS
WARNING - HAZARDOUS ENVIRONMENTS SYMBOL
This product is not specically 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.
!
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.
Not to be used in safety critical circuits, refer to the Pickering Interfaces’ terms & conditions of sale.
This module must not be used for the switching of Mains Circuits. For the switching of voltages up
to the module’s full specication, Secondary Circuit power supplies and the Device Under Test must
be fully isolated from the Mains Circuit and the safety earth.
The host chassis must be correctly installed and be connected to mains or factory safety ground,
please refer to your chassis installation manual.
Diagram Showing Separation Between The Mains Circuit and Secondary Circuit / DUT
For the purposes of this document, a Mains Circuit is an installation classied as Overvoltage
Category II up to 300V. Separation between the Secondary Circuit and Mains Circuit is achieved
by a transformer in which the primary windings are separated from the secondary windings by
reinforced insulation, double insulation, or a screen connected to the protective conductor terminal.
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.

WARNING
Only the correct SMA connector series should be mated with these modules. The 40-785 range uses
SMA-3.5, SMA-2.9 & SMA-1.8 connectors for 40, 50 & 65GHz respectively, 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 SMA connector’s nut is properly tightened to the correct torque with a
5/16 inch wrench. This should be 3-5 in·lbs (0.3 to 0.6 N·m) for brass, and 7-10 in·lbs (0.8–1.1 N·m) for
stainless steel connectors.

Default State Shown
Single slot version controls up to
3 remotely mounted microwave
multiplexers via interface cables
The 40-785 is suitable
for constructing complex
microwave switching networks
and provides a range of
switching congurations to suit
most applications. Connection
is by high performance front
panel mounted SMA style
connectors for 50Ωversions.
The 40-785 range of PXI microwave multiplexers are suitable for
switching 50Ω signals up to 40GHz. They are available in single
or dual 6 channel congurations, 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 multiplexers are
supplied with a 1.5m interface cable.
The panel mounted 50Ω terminated version occupies 4 slots for the
single version or 6 slots for the dual version.
A 75Ω version is available with a bandwidth of 4GHz and uses
Siemens 1.6/5.6 style connectors.
These modules give 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.
Easy Repair
To allow fast in eld repair, any relay may be replaced without
removing the module from the PXI chassis.

SECTION 2 - TECHNICAL DESCRIPTION
FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.2. The Microwave Multiplexer Module is powered by +12V and
+5V inputs via Compact PCI connector J1. The interface to the user test equipment is via the front panel mounted
SMA connectors. The module comprises a PCB which provides mounting for control logic, and a front panel which
provides mounting for the microwave relays (the remote -E option controls the relays via a 1.5m screened cable).
The relays are energised via control signals from relay drivers U10 and U11. The relay drivers are addressed by
PCI bridge U1, via output register U8, to output the required signal. PCI Bridge U1 is congured by EEPROM U2.

PREOPERATION CHECKS (UNPACKING)
1. Check the module for transport damage and report any damage immediately to Pickering Interfaces.
Do not attempt to install the product if any damage is evident.
2. Position the chassis relative to any other equipment the module(s) will connect with. Ensure the chassis is not
connected to the electrical supply.
3. Ensure that the designated area for the chassis containing the module is of at and solid construction to
withstand and support the combined weight of the module(s) and chassis.
SECTION 3 - INSTALLATION
!
Refer to the Warnings and Cautions at the front of this manual

SECTION 3 - INSTALLATION
SOFTWARE INSTALLATION
First install the appropriate Pickering PXI switch card drivers by running the installer program Setup.exe (provided
in a compressed zip le), either from the CD-ROM supplied, or by downloading the latest version from our website
pickeringtest.com - the recommended method. Setup is accompanied by a ReadMe le containing
additional installation information. A single installation covers all cards in the System 40, System 45 and System
50 ranges.
When installation completes, the installed drivers’ ReadMe le is offered for display. It can also be displayed
later using a shortcut on the Programs>>Pickering menu.
If you are not a LabVIEW user you should choose the “full” version, and once that has been installed run
the LabVIEW Runtime Engine installer via the shortcut on the Programs>>Pickering menu. In the absence of
LabVIEW the Runtime Engine is required to support the Pickering Test Panels application.

HARDWARE INSTALLATION
ELECTRICAL CONNECTION (CHASSIS)
1. The chassis must be electrically installed in accordance with local regional electrical codes by a qualied
engineer.
2. The chassis must be grounded.
Electrostatic discharge can damage the components on the module. To avoid such damage in handling the
board refer to page VII.
Ensure that there is adequate ventilation.
The module should be installed in accordance with the following procedure:
1. Ensure that the system is turned OFF but still connected to mains so that it remains grounded.
2. Choose an appropriate slot in the rack.
3. Remove the blanking plate for the chosen slot.
4. Ensure that the injector/ejector handle is in its downward position. Align the module with the card guides on
the top and bottom of the slot.
Do not raise the injector/ejector handle whilst inserting the module as the module will not insert properly.
5. Hold the handle whilst slowly sliding the module into the card guides until the handle catches on the injector/
ejector rail (refer to Figure 3.1).
6. Raise the injector/ejector handle until the module rmly seats into the backplane. The front panel of the
module should be ush with the front panel of the chassis.
7. Secure the front panel of the module using both screws to the chassis front panel mounting rails.
8. In a system employing a remote control interface to connect an external controller to a PXI chassis or to link
multiple chassis, power-up the system as follows:
a. For a system comprising an external controller and one chassis, power up the chassis before powering up
the external controller.
b. For a system comprising more than one chassis, turn ON the last chassis in the system followed by the
penultimate, etc, and nally turn ON the external controller or chassis containing the system controller.
9. For Pickering Interfaces modular LXI installation there is no requirement to use any particular power up
sequence.
