3.3 Analog Input Connections
USB-4716 supports 16 single-ended/ 8 differential (or combination)
analog inputs. Each individual input channel is software-selected.
analog inputs. Each individual input channel is software-selected.
3.3.1 Single-ended Channel Connections
The single-ended input configuration has only one signal wire for each
channel, and the measured voltage (Vm) is the voltage of the wire as ref-
erenced against the common ground.
A signal source without a local ground is also called a “floating source”.
It is fairly simple to connect a single-ended channel to a floating signal
source. In this mode, USB-4716 provides a reference ground for external
floating signal sources.

signal source and an input channel on USB-4716.
