Module Architecture - Pickering PXI 40-748 1 Series User Manual

SECTION 4 - PROGRAMMING GUIDE

MODULE ARCHITECTURE

The 40-747 series of PXI modules are arrays SPDT relays configured as 16-channel (40-747), dual 8-channel (40-
748) and quad 4-channel tree multiplexers. Energising a particular signal path energises the corresponding relays
to create a connection between the common and the required channel terminal. The multiplexer's architectures are
shown in the diagrams below:
