Operation Theorem •• 17
The cPCI/PCI-6208A provides an on board +15V power supply. Each
current output channel is a current source which is controlled by the
voltage of the corresponding channel. For example, voltage output
channel 3 control the current source channel 3. The output current
range is programmable. All the 8 current channels on cPCI/PCI-6208A
are controlled by one control register. The control voltage range is
always uni-polar 0~10V. There are three kinds of output current range.
Refer to the following table and Section 5.2.8 for programming the
current range by _6208_I2V_Control function.
