Gains and Ranges

2-4
A DAS-800 board measures analog input signals in the range of ±5 V.
Each DAS-801 or DAS-802 board contains a programmable gain
amplifier (PGA), which allows you to measure analog input signals in one
of several software-selectable unipolar and bipolar ranges. For each
channel on a DAS-801 or DAS-802 board, you can specify one of five
bipolar and four unipolar analog input ranges.
Table 2-1 lists the gains supported by DAS-800 Series boards and the
analog input voltage range for each gain.
