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.
