Channels may be configured to acquire data as singled-ended inputs or as differential
pairs. During differential acquisition, odd channels (1, 3, 5, etc.) are the positive input
and the even channels (2, 4, 6, etc.) the negative inputs. A channel pair consists of
two consecutive channels (1&2, 3&4, 5&6, etc.). Within a channel pair both channels
must be specified as single acquisition or both as differential acquisition.

Several input ranges for voltage and current are supported. Ranges that include both
negative and positive values are referred to as bipolar ranges throughout this
document. Ranges that include only positive values are referred to as unipolar.
Within a group of 8 consecutive channels, all 8 channels must be from either 8
voltage or 8 current sources. If part of a voltage group, a channel may be any of the
allowed voltage ranges and if in a current group a channel may be any of the allowed
current ranges as long as all 8 are either voltage ranges or all 8 are current
