ABSTRACT:
A test and measurement system may include a light source coupled to a 1×(N+M) switch that supplies signals to devices under test as well as reference channels. The outputs from each channel of each device under test, as well as the reference channels, are provided to M 2×(N+1) routing switches in one embodiment. The routing switches are then coupled to M channel detector modules. As a result, it is not necessary to connect and disconnect the switches, making long-term environmental tests viable while avoiding losses from disconnecting and connecting switches in the course of ongoing testing.
