Signals

Analog input

You can connect up to eight single-ended analog inputs (CH0 to CH7) or four differentials (CH0H/CH0L to

CH3H/CH3L).

Single-ended configuration

When configured for single-ended input mode, eight analog input channels are available. Each analog input has

11-bit resolution (due to restrictions imposed by the A/D converter) and offers a ±10 V analog input range.

The input signal is referenced to signal ground (

AGND), and is delivered through two wires:

 Connect the wire carrying the signal to be measured to

CHx.

 Connect the second wire to

AGND.
