SAIA PCD2.A220 Channel contact module

Detailed information

SAIA PCD2.A220 Channel contact module

In a similar way as described in Section 3.3, any one of the DAC outputs can be selected, via the test MUX and analog test switch (Figure 3.4-3), to be routed out a separate dedicated analog bus entitled Test Bus 1. This test bus is a dedicated input to any PCD2.A220 that resides in the same SAIA Analog Backplane. This test bus can be used by the PCD2.A220 Board to verify each of the 32 multiplexer channels by multiplexing the test bus input, one at a time, throughout a selected channel of the PCD2.A220 onto the PCD2.A220 ADC Board. For more details, refer to the PCD2.A220 Instruction Manual and the SAIA High Level Analog Data Acquisition System Manual.

This provides an input to the ADC Board which is similar to a differential signal called pseudo differential. Pseudo differential solves some of the common mode error problems associated with single-ended signals. The input to the ADC Board is referenced to the ground of the DAC Board instead of the local ground at the ADC Board, effectively cancelling out common mode errors associated with different ground potentials at each of the boards.
