Analog Input Switch; Input Modes Of The Analog Inputs; Simple Mode - Addi-Data APCI-3003 Technical Description

Functions of the board
Please note: During the switching of the voltage range from unipolar to bipolar or
from bipolar to unipolar there is a longer settling time of the measuring chain (see

8.2.4 Input modes of the analog inputs

On the board are 4 differential channels available for the analog inputs. The
acquisition can be realized in the following modes

1) Simple mode

2) Scan mode
3) Sequence mode
4) Auto refresh mode
1) Simple mode
The software initializes and starts the A/D conversion and after this step it reads
the digital value of one or more channels. For more detailed information please
