Operation Theorem
The operation theorem of the functions on PCI-9812/10 card is
described in this chapter. The functions include A/D conversion and
digital input. The operation theorem will help you to understand,
opesate and program the PCI-9812/10.
5.1 A/D Conversion Procedure
Before programming the PCI-9812/10 to perform the A/D
conversions, you have to understand the following concepts:
l
A/D conversion procedure
l
A/D signal source control
l
A/D trigger source control
l
A/D clock control
l
A/D data transfer mode
l
A/D data format
When using an A/D converter, users should know about the
properties of the siginal to be measured at first. Users can decide
which channels to use and connect the signals to the PCI-9812/10.
In addition, users should define and control the A/D signal sources,
including the A/D channels, A/D gains, and A/D siginal types.
Please refer to section 5.2 for A/D signal source control.
