WARNING - Hazardous Environments Symbol

This product is not speciﬁcally 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.

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:

• 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.

• 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.

• Outer clothing worn must be unable to generate static charges.

• Printed Circuit Boards (PCBs) ﬁtted with these devices must be stored and transported in anti-static bags.

Warnings & Cautions

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 PXI/PXIe/LXI 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 - Product Documentation Symbol

Suitably qualiﬁed & trained users should ensure that the accompanying documentation is fully read 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.

WARNING

Only the correct connector series should be mated with these modules. The modules in the 4x-890 range using SMA

connectors should only be mated with the correct SMA type, failure to do so may result in damage to the connector.

Also, it is important that the connector’s nut is properly tightened to the correct torque. For SMA connectors, this

should be with a 5/16 inch wrench and be 3-5 in·lbs (0.3 to 0.6 N·m) for brass, or 7-10 in·lbs (0.8–1.1 N·m) for

stainless steel. For N-type connectors, this should be with an 18mm wrench and be 15 in·lbs (1.7 N·m).

An example conﬁguration could include a combination of two

SP6T plus one SPDT relay that can be externally cabled to create

a SP12T multiplexer for frequency ranges where a dedicated

12:1 multiplexer is not available.

Flexible solutions can also reduce the chassis slot count by

permitting different relay types to be ﬁtted in a single module.

Each ﬂexible build will be assigned a speciﬁc part number in the

4x-890 series to provide traceability and to ease the reordering

process.

Microwave Switch Design Tool (MSDT)

The MSDT is an on-line application accessed via the Pickering

interfaces website that can be used to generate front panel

solutions for ﬂexible products. Users can select from the

full range of microwave relays then add LED indicators and

graphical features such as components identiﬁers / logos to

create a panel layout suited to the application.

Section 1 - Technical Speciﬁcation

LED Energised Path Indicators

Space permitting, each microwave relay ﬁtted to a 4x-890

module has associated frontpanel LED indicators to show the

current energised path through the relay, as illustrated in the

ﬁgure above. This signal path indication greatly simpliﬁes the

debug of test application software.

Manual Control

The 4x-890 is supplied with soft front panels for each of the

ﬁtted relays, as shown here. These enable graphical manual

control of the switches to simplify application software

development and debug.

Easy Repair

To facilitate fast in-ﬁeld repair, wherever possible we ﬁt relay

types that may be quickly replaced by simply withdrawing

them through the front panel.

Conﬁguration Restrictions

Whilst offering a high degree of ﬂexibility in relay population

there are some restrictions applicable to the ﬂexible

conﬁgurations.

Mechanical - the maximum number of chassis slots occupied by

a single module is six. The relay physical sizes varies between

switch types, for details refer to the user manual. Alternately, to

assist with visualising the panel layout Pickering’s Microwave

Switch Design Tool (MSDT) online application can be used to

deﬁne the relay quantities, types and positions.

Electrical - the driver card has twenty-four control lines,

grouped both in banks of six or individually with each relay

coil typically requiring a single control line. Each SPDT or

transfer switches is controlled by an individual drive line.

For multiplexers, a single six channel bank is required for

SP4T and SP6T multiplexers with higher channel count

multiplexers controlled via multiple banks.

Due to the ﬂexible nature of the product range it is

recommended that your local sales ofﬁce is contacted to

review your requirements as this will allow for the most

efﬁcient relay loading to be determined.

Relay Cycle Counting

To aid with module “health” monitoring all versions are

provided with a relay cycle counting cycle feature. The

number of operations per contact are stored on the module

and can be used to determine if a relay is approaching EOL.

This information could allow system connections to be

revised so that signals applied to heavily used contacts are

swapped with lightly used contacts to prolong the working

life of the relay(s).
