Dow-Key Spotlight on Complex New Crossbar Switch Series

Part of Dow-Key’s New Line of Matrix Switches, the CB-Series is an Advanced
Product Geared for Solving Difficult Test Setups and Switching Obstacles

Keeping in line with their other new product releases for 2012, Dow-Key Microwave is excited to highlight another full featured product, the CB-Series next generation matrix switch. The CB-Series, a non-blocking crossbar system, creates a one-to-one relationship by allowing any input to be connected to any unique output. Dow-Key developed this next generation crossbar matrix switch system as a switch solution for more complex test setups and signal routing. The CB-Series allows for testing multiple UUT (units under test) with many input and output signals or high speed communication buses without having to connect and disconnect them from the setup. As well, the CB-Series crossbar switching 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.
We are excited to put forward a platform that gives the user more control and more flexibility in ways of switching RF signals between many input and output ports and yet being budget friendly in this economy,” stated Dow Key representative Sara Nazemzadeh. “Software options such as manual control, Ethernet, RS-232, USB and even a built-in web interface are all available in a single COTS solution and features such as keeping track of the cycle count or adding and removing switches to support field repairability and future needs are new to this generation of switching solutions.”
Dow Key’s CB-Series crossbar switching systems typically start from between 2×2 up to 12×12 and can be customized to support larger configurations.
