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.

anti-static bags.

CAUTION - PRODUCT DOCUMENTATION SYMBOL

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.

RF MUX

For applications that

require SMB or MCX

connectors, Pickering

offer newer designs

with signiﬁcantly

improved

performance.

The 40-875 (50 Ω)

and 40-835 (75 Ω)

are 16-Channel

multiplexers with

bandwidths to 3 GHz

The 40-747-731 is a single 16 to 1 RF 75 Ω multiplexer

module ﬁtted with 1.0/2.3 connectors and occupying a

single PXI slot.

Applications for the 40-747-731 include routing high

frequency signals to and from oscilloscopes, analyzers,

signal generators and synthesizers, telecoms tributary

switching, video/audio switching and switching high

frequency logic signals.

The 40-747-731 is supplied with drivers that allow the

module to be supported in all popular PXI software

environments. The module can also be supported in

Pickering Interfaces’ LXI/PXI Modular Chassis, allowing

users to choose an LXI or PXI switching platform while

retaining the same high performance characteristics and

driver environment.
