3.2 Back Panel PCB
The Back Panel PCB is installed in the rack just as its name indicates, to the rear panel
of the rack or instrument enclosure. It is secured to the rear panel with three flat head
screws and with the BNC connector nuts. A Back Panel PCB is required for each
Measuring Channel installed in the rack. Its purpose is to provide external I/O
connections for each Measuring Channel and transmit them to the Back Plane PCB.
