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.

•t 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.
