Single-ended connections
A single- ended connection is applicable when the analog
input signal is referenced to a ground and can be shared
with other analog input signals. There are two different
types of single- ended connections, which are RSE and NRSE
configuration.
• Referenced Single- Ended (RSE) mode
In referenced single- ended mode, all the input signals are
connected to the ground provided by the U2300A series
DAQ and suitable for connections with floating signal
sources. The following figure illustrates the RSE mode.

NOTE
When more than two floating sources are connected, these sources are
referenced to the same common ground.
