CHAPTER 4 APPLICATIONS
4.1 ANALOG INPUT CONNECTION
It is important to understand the connections between
the type of input signals, how to use them effectively, and
how to avoid ground loop. Misuse of the inputs is the most
common difficulty users experience in applying and
obtaining the best performance from data acquisition
systems. This chapter provides useful information
concerning how to connect analog signals with AR-
B3001 correctly in different types of data acquisition
applications.
The analog input connection to AR-B3001 is jumper
selectable to fit differential or single-ended analog signals.
This can be configured by inserting JP1 to right
(differential) or left (single) position. A single-ended
signal has only one signal wire for each channel. This
type of signal does not have a ground connection at the
signal source. This type of signal is also called a "floating
source". A standard connection of a floating signal is
shown in figure 4-1.
