Switching module within a signal distribution system.

摘要

The signal distribution function in a signal distribution system (34) is performed in a switching matrix (12, 46) under the control of a hybrid controller (12). With respect to the switching matrix (46), there are approximately 120-140 interface I/O connections available such that an equipment under test (16) can be selectively connected to any one of a plurality of test instruments (24). The relays (52, 56) within the switching matrix are selectively activated such that a signal path connecting the equipment under test to a particular test instrument can be accomplished with a minimum amount of switching path conflicts.
