CXAR SERIES

COAXIAL SWITCHING SYSTEMS
The CXAR Series are Computer Controlled Coaxial Switching Systems for 50 or 75 ohm RF Signals
up to 1.6 GHz, or Low Leakage signals down to 100 Femto amps. These systems are typically
used to configure 1xN multiplexers. Both Mainframes and Expansion Chassis are offered and
hold a variety of different switch modules to form the desired configuration.

FEATURES:

CXAR/32 Mainframe with pushbutton manual control

•t RF Systems with Bandpass from DC to 1.6 GHz, 50 or 75 Ohm Impedance and low crosstalk.
•t Low Leakage modules for current measurements down to 100 femto amps or resistance up to 100 terra ohms.
•t Low cost reed relay 1 or 2 pole coaxial modules for high speed, long life switching of signals below 100 MHz.
•t Computer Control from Ethernet LAN, IEEE488 BUS, RS232 Serial, USB or TTL.
•t LED Front Panel Display and Status Feedback to Computer for visual indication and debugging.
•t Manual Control Option for use without computer control.

CHASSIS:

The CXAR Units are 19" rack mounted chassis, and are available as either Mainframes or Expansion Chassis pre-wired to accept
any of the CXR Series of Coaxial Switch Modules. All chassis have front panel LEDs showing latched switch points and have I/O
connectors mounted through the rear panel.
CXAR/16 Mainframe or -E Expansion Chassis - 16 relay drives allow for two 8x1 modules or four 4x1 modules.
CXAR/32 Mainframe or -E Expansion Chassis - 32 relay drives for four 8x1 modules, eight 4x1 modules or combinations.
CXAR/64 Mainframe or -E Expansion Chassis - Up to 64 relay drives. Control up to 16 4x1 modules in a 5.25" high chassis.
CXAR/128Mainframe or -E Expansion Chassis - Up to 128 relay drives. Control up to 16 8x1 modules or 8 16x1 modules
in a 7" high chassis.

SWITCH MODULES:

There are five series of Switch Modules. Each series has design features tailored to specific needs.

CXR Series use coaxial reed relays and are available with a bandpass up to 200 MHz. BNC or Screw Terminal Connectors.
CXR-G Series use armature relays in a tree configuration and have a bandpass exceeding 1 GHz. BNC or SMA Connectors.
CXR-2A Series use two pole relays to switch balanced line signals and have bandpass up to 200 MHz. BNC's or Twin-ax.
CXR-LL Series use single pole low leakage relays for currents as low as femto amps or resistance as high as terra ohms.
CXS Series use solid state relays for high reliability 50 or 75 ohm switching.

CONTROL MODULES:

All systems available with Ethernet LAN, IEEE488 (GPIB) & RS232 and USB (standard), or TTL Control (optional).
