4 ANALOG CONNECTIONS
4.1ANALOG INPUTS
Analog signal connection is one of the most challenging aspects of applying a
data acquisition board. If you are an Analog Electrical Engineer then this
section is not for you, but if you are like most PC data acquisition users, the
best way to connect your analog inputs may not be obvious. Though complete
coverage of this topic is well beyond the scope of this manual, the following
section provides some explanations and helpful hints regarding these analog
input connections. This section is designed to help you achieve the optimum
performance from your PCM-DAS16x/12 series board.
Prior to jumping into actual connection schemes, you should have at least a
basic understanding of Single-Ended/Differential inputs and system
grounding/isolation. If you are already comfortable with these concepts you
may wish to skip to the next section (on wiring configurations).
4.1.1 Single-Ended and Differential Inputs
The PCM-DAS16x/12 provides either 8 differential or 16 single-ended input
channels. The concepts of single-ended and differential inputs are discussed
in the following section.
