EADS North America Test and Services Racal Instruments™ 1260-75A/B 100 MHz RF Multiplexer The Racal Instruments™ 1260-75 is ideal for switching wide-band signals up to 200 MHz. It is intended for use with function/pulse generators, universal counter/ timers, oscilloscopes and other instruments where high frequency or fast pulse signals are switched. A major application is in the switching of video signals. Key Features • 1260-75A configurable as: ––Eight 1x4 ––Four 1x9 ––Two 1x19 ––One 1x39 • 1260-75B configurable as: ––Sixteen 1x4 ––Eight 1x9 ––Four 1x19 ––Two 1x39 ––One 1x79 • 100 Mhz bandwidth, usable over 200 MHz with excellent crosstalk and isolation specs Product Information The 1260-75A consists of eight 1x4 75 Ω multiplexers and the 1260-75B consists of sixteen 1x4 75Ω multiplexers. These multiplexers are bi-directional and configurable via software. This makes reconfiguration very easy and eliminates the need to disassemble the module. Relay coil currents are monitored to provide selectable confidence checking which gives the user additional assurance of proper relay operation. The 1260-75 is controlled by the Racal Instruments™ Option 01 message-based interface, or the Option 01T messagebased and register-based interface. The coaxial connector housing (shell) is supplied with the 1260 75A/B. Coaxial pins and cables for this module are also offered. Coaxial cables have been tested up to a 1 GHz bandwidth and are available in 2, 6 and 12 foot lengths with a coaxial pin at each end. • Software configurable • Coaxial interfaces ECO# 2011-EADSTS-02-01-11-38-MU.
