Differential Input Mode
The differential input mode provides two inputs that respond
to the difference of the signal voltage. The analog input of
the U2300A series DAQ has its own reference ground or
signal return path. The differential mode can be used for the
common- mode noise rejection if the signal source is
ground- referenced. The following figure shows the
connection of ground- referenced signal sources under
differential input mode.
