3 Board Configuration.
actually channel specific and consists of many parameters that change across
the various boards and channels. The software contains a configuration panel
which is discussed separately. The individual board documentation explains
these parameters in more detail.

values of the different stages of the signal path for a respective physical channel.
For example, in the case of the SP1202S01RB, pane 1 is used to display the
Sensor output value in terms of its own sensor units, pane 2 displays the
sensor’s output voltage in terms of volts, pane 3 displays the ADC input voltage
level, and pane 4 displays the ADC’s output code value (refer to Figure 3-2:
SP1202S01RB). All of these measurements are referenced to the ADC output
value of physical channel 1.
