EADS North America Test and Services Racal Instruments™ 1260-54 MATURE 1.3 GHz RF Multiplexer Module The Racal Instruments™ 1260-54 is ideal for high performance RF applications. Key Features • Configurable as six 1x4 tree multiplexers • Excellent crosstalk, isolation and VSWR performance to 1.3 GHz • Low noise performance supports switching of low-level RF signals • Ideal for VHF/UNF matrix building block • Optional termination of input signals • Excellent for oscilloscope or time interval counter measurements Product Information The 1260-54 consists of six independent banks of channels configured as 1x4 multiplexers. The tree configuration eliminates the effect of unterminated stubs which would otherwise severely limit bandwidth performance. Unused inputs may be terminated into optional on-board 50 Ω impedances. The 1260-54 can be used for switching signals from oscilloscopes, spectrum, network or distortion analyzers to a unit under test. The 1260-54 consists of six of the above 1x4 tree multiplexers. Each channel has the capability of being terminated to an optional 50 Ω terminator. One tree is shown. Only one connection at a time can be made to each common bus. Unused inputs may be terminated into optional terminators (purchased separately).There is also a fifth, no connect, position for each bank for situations when no signal is desired on the common bus. Relay coil current monitoring is available to provide confidence checking. This gives the user assurance of proper relay operation. The 1260-54 is controlled by the Racal Instruments™ Option 01 message-based interface, or the Option 01T messagebased and register-based interface. ECO# 2011-EADSTS-1xx-xx-xx-MU.
