B.1

Analog Input Operation 

This section describes the following features of analog input that can help you realize
how to configure the functions and parameters to match various applications. 

AI Hardware Structure 

Analog input ranges and gains 

Analog data acquisition mechanism 

Analog input acquisition modes 

AI SCAN/CONV clock source 

AI trigger sources 

Analog input data format 

B.1.1

AI Hardware Structure 

The AI conversion hardware structure includes four major parts: 

Auto-scan multiplexer

 routes the analog input signals into AI converter chan-

nel by channel in a software-defined sequence. 

PGIA

 (Programmable Gain Instrument Amplifier) rectifies the input range and 

amplify/alleviate input signal to match the input range of A/ D converter. 

AI converter

 conceives the rectified voltage from PGIA and transfers it into the 

corresponding digital data format. 

Trigger/Clock control logic

 enables/disables the whole process and deter-

mines acquisition timing interval.
