com scales).
The photodiodes are accompanied with precision
amplifiers plus additional circuitry.
The monitor channel is used to drive a constant current source for the highly collimated IR illumination system.
Functional Description Background
The 13 signal channels are set up as: 1.
Two precision defining signals (A0, A09), which are two 90° electrical shifted sine, cosine signals.
These signals are condit...
