Theory of Operation
Functional Overview
National Instruments Corporation
This chapter includes an overview of the PC-LPM-16PnP board and
explains the operation of each functional unit making up the board. This
chapter also explains the basic operation of the PC-LPM-16PnP
circuitry.
The following are the major components making up the
PC-LPM-16PnP:
•
PC I/O channel interface circuitry
•
Analog input and data acquisition circuitry
•
Digital I/O circuitry
•
Timing I/O circuitry
You can execute data acquisition functions by using the analog input
circuitry and some of the timing I/O circuitry. The internal data and
control buses interconnect the components. The theory of operation for
each of these components is explained in the remainder of this chapter.
The block diagram in Figure 3-1 shows a functional overview of the
PC-LPM-16PnP.
