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.
