block
•t Optional termination of input
signals
•t 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.
