1.10.1 ICB (Inter-Connection Board)
ICB is an interconnection board consisting of six 64-pin ICB bus slots to accommodate printed
circuit boards (PCB of Euro standard format).
1.10.2 PSV/PIC Combination
The PSV card (signal processing) carries out the A/D conversion and the real evaluation of each
measuring signal.
The PIC card (Physics Interface Card, page 1-38) supplies the photometer components and the
individual sensors with the individual required operating voltages and transmits all measuring
signals to the signal processing unit PSV.
1.10.3 DSP (alternitavely to PSV/PIC Combination)
The DSP card (Digital Signal Processing) page 1-39) supplies the photometer components and
the individual sensors with the individual required operating voltages and carries out the A/D
conversion and the real evaluation of each measuring signal.
