Pre-configured RF/microwave switch system
BROADBAND SIGNAL ROUTING
7116-MWS RF/Microwave Switch System
1×16 Multiplexer
The Model 7116-MWS is a fully assembled 16-Channel RF/Microwave Switch System designed to simplify
controlling high frequency switching. It employs the IEEE-488-compatible Model 7001 Switch Mainframe as
a switch controller as well as electromechanical coaxial relays with a bandwidth from DC to 18GHz.
Applications include production and laboratory testing of a variety of communications devices and systems.
Simple Setup and Control
All input and output connections are easily accessible from the front panel, so system maintenance
and reconfiguration is fast and easy. In addition, the non-volatile memory in the Model 7001 is pre-
programmed in a 1×16 multiplexer switching pattern, allowing users to begin operating it immediately.
High Signal Integrity
All RF/microwave relay interconnections are implemented using low-loss, semi-rigid RF cabling to ensure
high signal integrity. Signal paths are of equal length to ensure similar transmission line characteristics and
performance in every channel. The relays used provide high isolation to minimize channel crosstalk. The
Model 7116-MWS’s combination of low insertion loss and high isolation ensures high quality measure-
ment pathways for signal routing and measurement.
Expandable
The Model 7001 mainframe has a spare card slot
available that allows control of up to 40 additional
switch channels. More than 30 cards are available
to expand the Model 7116-MWS’s switching capa-
bilities to include low frequency, general purpose,
optical, or additional RF switching.
Industry-Leading IEEE-488
Controller
The Keithley Model 7001 Switch Mainframe includ-
ed in the Model 7116-MWS has a distinctive front
panel vacuum fluorescent display that provides
continuous, real-time information on the status of
all switches. Intuitive front panel controls allow the
system to be manually operated, speeding and
simplifying test verification and troubleshooting.
Up to 100 complete switch patterns can be pro-
grammed in the Model 7001’s non-volatile
memory.

Keithley Design Assistance
For applications that require a larger switching system or an unusual switch
configuration, Keithley can assemble a customized turnkey signal routing sys-
tem to meet unique specifications, including operating frequencies up to
40GHz. For example, systems can be assembled with microwave relays, pro-
grammable attenuators, couplers, isolators, amplifiers, power dividers/
combiners, etc. Keithley also offers high capacity switch controllers that can
accommodate up to 400 switches. Contact Keithley’s Applications Engineering
team for additional information.
