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.

40-755-x10 10 off SP4T RF MUX
Switching Diagram (Default Switch Paths Shown)
The 40-755 is a high density RF multiplexer available in
50 Ω and 75 Ω variants with up to 10xSP4T switches in
a single PXI module. It is available with two connector
options; SMB that provides a frequency range of 1.8 GHz
(50 Ω) / 1.3 GHz (75 Ω), or multiway which limits the
bandwidth to 1.3 GHz but offers a high density solution
occupying one PXI slot. The connectors used are fully
supported by the range of Pickering Interfaces connection
solutions.
40-755 RF Multiplexer Range:
10 off SP4T, 50 Ω, 1.8 GHz, SMB, Dual PXI Slot
10 off SP4T, 50 Ω, 1.3 GHz, Multiway, Single PXI Slot
5 off SP4T, 50 Ω, 1.3 GHz, Multiway, Single PXI Slot
4 off SP4T, 50 Ω, 1.8 GHz, SMB, Single PXI Slot
10 off SP4T, 75 Ω, 1.3 GHz, SMB, Dual PXI Slot
10 off SP4T, 75 Ω, 1.3 GHz, Multiway, Single PXI Slot
5 off SP4T, 75 Ω, 1.3 GHz, Multiway, Single PXI Slot
4 off SP4T, 75 Ω, 1.3 GHz, SMB, Single PXI Slot
The module offers low insertion loss and low VSWR through
its usable frequency range and each multiplexer has been
designed to have path independent loss.
The array of SP4T switches can be connected into alternative
configurations through the use of external cabling.
The 40-755 is supplied with drivers that allow the user
to support the module in all popular PXI software
environments. In addition, the module can be supported in
all Pickering’s LXI Modular Chassis, allowing the use of a
PXI or LAN controlled switching solution with the same high
levels of performance.

FUNCTIONAL DESCRIPTION
A functional block diagram is provided in Figure 2.1. The RF Multiplexer Module is powered by 3.3V and 5V inputs
via Compact PCI connector J1. The interface to the user test equipment is via the front panel mounted coaxial
connectors which can be - depending upon the model number - 26-pin multiway or individual SMB coaxial connectors.
The module comprises a PCB populated with high quality electro-mechanical relays arranged as a four, ve or ten
banks of 4-channel tree multiplexers. The relays are energised via control signals from relay drivers U50 and U51.
The relay drivers are fed with serial data from PCI bridge U1 via isolators U59 and U60. Module conguration is
determined by data stored in EEPROM U3, the PCI Bridge U1 is congured by EEPROM U2.

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.
