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.

PXI 6 U Expandable 250 MHz 16x16 RF Matrix 45-720A

ISSUE 7.1 APR 2020

y16x16 Coaxial Matrix

y250 MHz Bandwidth

yHigh Quality Ruthenium Reed Relays

yChoice of Front Panel Mounted Coaxial Connectors

yAvailable in 50 Ω and 75 Ω Versions

yUses High Reliability Reed Relays

yVISA/IVI Drivers Supplied for Windows

y3 Year Warranty

The 45-720A module is a 6 U 16x16 RF Matrix suitable for

switching frequencies beyond 250 MHz. It is available in

50 Ω and 75 Ω versions with a choice of coaxial connectors.

It is intended for the easy construction of high performance

bi-directional matrix switching systems.

Automatic isolation switches are located on all input and

output connections. These are used to disconnect unused

signals from the external test ﬁxture to maximize isolation

and RF performance.

Typical applications are switching signals to high speed

digitizers. The matrix is constructed using high reliability

ruthenium electro-plated reed relays, with an operational

life of >108 to give maximum switching conﬁdence with long

service and stable contact resistance.

Matrix Operation

The 45-720A is a true 16x16 high density

matrix, any combination of cross-points

may be selected. Only the signal is

switched, all grounds are common. Loop-

thru is included on X signals.

Easy Expansion with Automatic Loop-Thru

All unused X input channels are

automatically switched to the

corresponding “Loop-thru” output

connection. This allows for simple

expansion (with a little performance loss)

and permits the user to place matched

terminations on the outputs if required.

Matrix Expansion

Larger matrices may be constructed by daisy-chaining the X signals from multiple modules, for example, six modules form a 96x16

matrix (1536 crosspoints). Expansion is achieved by interconnecting Xout (Loop-thru) of one matrix to Xin of the next using coaxial

cables as shown below. It should be noted that the operating bandwidth will reduce slightly as the number of modules is increased.

Matrix Modules Can be Daisy-Chained to
