5.9_9112_AD_Set_Range

uDescription

This function is used to set the A/D analog input range by means of writing data to the A/D range control register. There are two factors will change the analog input range - Gain and Input type.

The Gain can be choice from 0.5, 1, 2, 4, and 8 . The input type is either Bipolar or Unipolar.

The initial value of gain is '1‘ and input type is bipolar, which are pre-set by the PCI-9112 hardware. The relationship between analog input voltage range, gain and input mode are specified by following tables:

** this table is suitable for PCI-9112 card.

			Input type
AD_INPUT	GAIN		(Bipolar or	Input Range
			Unipolar)
AD_B_5_V	1		Bipolar	±5V
AD_B_2_5	2		Bipolar	±2.5V
