NEXT GENERATION
SWITCH MATRIX
ELECTROMECHANICAL SOLUTIONS
OUR EXPERIENCE, YOUR SWITCH SOLUTION
SINCE 1945
MS-SERIES
BETTER. FASTER. MORE MODULAR.
Multiple Switches: The matrix is populated with individual RF switches
Commercial-Off-The-Shelf (COTS) solutions supporting the aerospace, military, transportation,
and communications industries for signal routing and ATE applications.
Next Generation Matrix Platform
The next generation platform is engineered around a flexible and efficient modular system architecture comprised of a series
of brackets, panels and electronic-boards that are universal among all Dow-Key electromechanical models. Commercial-OffThe-Shelf (COTS) solutions are not only cost effective, but can also easily be re-configured by adding RF switches to a single
enclosure – from simple to complex combinations. This new platform is easily field upgradable and repairable.
The MS-series populated with individual switches allows the user to
control multiple coaxial switches easily through software and gives the
user the flexibility to add as many switches as needed (limited to the size
of the enclosure) on the rear panel starting with a 19” 1RU chassis up
to 4RU (and larger enclosures for custom designs). For 2RU and larger
enclosures, the switches can also be installed inside the chassis.

MP-SERIES
Multiplexer: An input goes to multiple outputs OR multiple inputs are routed to a single output
The multiplexer (MUX) has the capability to route one input to as many as N outputs (it is bidirectional). It is offered with operating
frequencies of 18 GHz and 26.5 GHz (terminated and non-terminated) depending on the type of configuration needed.
1x16 MUX
Typical designs are 1x13 up to 1x143 MUX and can be customized
to support a larger MUX.

CB-SERIES
Crossbar (non-blocking): Any input can be connected to any unique output (ONE-TO-ONE relationship)
For more complex test setups and signal routing, the CB-series crossbar
matrix is an excellent choice. It allows testing multiple UUT (units under
test) with many input/output signals or high speed communication buses
without having to connect and disconnect them from the setup.
A crossbar system can route any input signal to any output port such
that the path between the I/O ports is unique at any given time.

MS-ENET
The MS-ENET is a kit with hardware and software allowing the software savvy user to control a set of CAN bus switches via
Ethernet (TCP/IP), RS-232 serial ports, USB port and HTTP protocol (built-in website provided). It is offered with Dow-Key
SCPI commands that gives the user the flexibility to control switches as needed. CAN bus switches are to be purchased
separately.
MS-GPIB
The MS-GPIB is a kit with hardware and software that allows the user to control a set of CAN bus switches via GPIB
(IEEE-488) parallel port and RS-422 serial port. Dow-Key SCPI commands are provided for controlling switches. CAN bus
switches are to be purchased separately.
FO-SERIES/ FI-SERIES
Fan-Out: Any input can be connected to one or multiple outputs simultaneously
Fan-In: One or multiple inputs can be connected to an output simultaneously
FO-SERIES
For more advanced RF switching where the input ports need to be routed to all output ports simultaneously, a Fan-Out design
is preferable. The design uses power dividers at inputs (divides the input signal to all outputs) and amplifiers (if required).
Gold Package
An example would be a 4x4 up to 12x12 fan-out switch matrix, which can be customized with additional components
MS-6101-ENET / MS-6101-GPIB
The MS-6101 controller offers an ideal switch setup allowing anyone to build their own matrix solution. The 1RU controller
is outfitted with 24 RJ-11 ports on the back that support 24 CAN bus switches and can be expanded to support additional
switches as needed. It has all the great software features as the other COTS models and is equipped with LCD/Keypad manual control on the front along with redundant power supplies. The ENET option includes Ethernet, RS-232, USB, and HTTP,
and the GPIB option includes IEEE-488 (GPIB) and RS-422. CAN bus switches are to be purchased separately.

or support a larger configuration.
FI-SERIES
A Fan-In switch matrix combines all the input signals and routes them to an output simultaneously. Thus, the design has combiners at the output ports and amplifiers (if required).
