Specifications

Analog Sense SCPs Analog sense SCPs connect signals at the faceplate connector and pass these signals
(most with signal amplification and/or filtering) to the analog multiplexer and thus
to the A/D for measurement. Here the primary signal path is along the analog Hi
and Lo lines. The SCP Bus carries digital signals to control the programmable
parameters on the VT1503A and VT1510A.
