Theory of Operation

for DaqBoard/2000 and /2000c Series Boards

As implied by the following matrix, the operational material does not apply globally to every

DaqBoard/2000 Series board or /2000c Series board. For example, boards /2002, /2003, /2004, and their

respective compact-PCI counterparts have no analog input.

For ease of understanding, each board is discussed independently, following the matrix. Note that pinouts

are provided in chapter 2.

Analog Input

Channels

Analog Input signals enter

through P4 , go to MUX, to

PGA, to Gain & Offset

Amplifier, then to Analog-

to-Digital Converter (ADC)

Analog Output

Channels

Digital Signals go through

Digital-to-Analog

Converters, then through
