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 System 10/20 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. Printed Circuit Boards (PCBs) tted with these devices must be stored and transported in

anti-static bags.

CAUTION - PRODUCT DOCUMENTATION SYMBOL

Suitably qualied & 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.

GPIB RF Multiplexer Module 10-740A

ISSUE 5.2 JUL 2019

• Dual 8 to 1 R.F. Multiplexer with 150MHz

Bandwidth

• 50Ω Characteristic Impedance

• Conﬁgurable as 16 to 1 Multiplexer with

Reduced Bandwidth

• Front Panel Mounted BNC Plugs

• Front Panel Indicator LEDs

• Suitable for Many Screened Low Frequency

Applications

Common

Dual 8-Channel RF Multiplexer Mode

Alternative 16-Channel RF Multiplexer Mode

Model 10-740A is a dual 8 to 1 RF Multiplexer with a bandwidth

up to 150MHz. The 10-740A may also be congured (via internal

DIP switches) as a 16 to 1 multiplexer but with reduced RF

performance. The multiplexer has a characteristic impedance of

50Ω.

The 10-740A is also suitable for low frequency applications

requiring BNC coaxial switching. It may be operated as a

normal RF multiplexer (with only 1 channel selected at a time),

alternatively 2 or more channels may be simultaneously selected

(but with much reduced RF performance).

Applications include routing high frequency signals to and from

oscilloscopes, analyzers, signal generators and synthesizers,

video/audio switching, switching high frequency logic and many

other situations involving coaxial or guarded switching.

Programming

The multiplexer module is simple to program:

ARESET a Open all channels on device a

DELAY t Force a minimum delay of tmilliseconds

between two instructions

RESET Open all switches on all modules

VIEW? a View status of device a

CHAN a,c Select channel con multiplexer a.

When in dual 8 to 1 mode the address is

prexed by 1 or 2.

CHAN a,c,s Multi-channel selection argument s

allows

opening/closing of any combination

of channels, but with reduced RF

performance.
