Signal Connections 27
Figure 3-1: Single-Ended Connections
In single-ended configurations, more electrostatic and magnetic
noise couples into the single connections than in differential con-
figurations. Therefore, the single-ended connection is not recom-
mended unless minimal wire connections are necessary.
Differential Measurements
Differential Connection for Grounded-Reference Signal
Sources
The differential analog input provides two inputs that respond
to the signal voltage difference between them. If the signal
source is ground-referenced, the differential mode can be used
for the common-mode noise rejection. Figure 3-2 shows the
connection of ground-referenced signal sources under the dif-
ferential input mode.
