Introduction
The PCI-6308 series products are isolated analog output cards. The PCI-
6308 series includes the follow three cards:
l PCI-6308V: Isolated 8-CH voltage output card
l PCI-6308A: Isolated 8-CH voltage and current output card
l PCI-6304V: Isolated 4-CH voltage output card
The PCI-6308V is a high-performance, 12-bit analog output board with PCI
interface. The PCI-6308V provide 8 identical voltage output channels, with
each channel capable of: (1) bipolar ±10V voltage outputs; (2) unipolar
0~+10V voltage output; and (3) unipolar 0 to user defined voltage output.
The DA chip used is the DAC-4814AP. A state-of-the-art, fully monotonic,
digital to analog converter. This device employs ultra-stable nichrome (NiCr)
thin-film resistors to provide monotonicity, low distortion, and low differential
linearity error over long periods of time.
The PCI-6304V is available to large quantity OEM only. It is fully compatible
with the PCI-6308V, but has four voltage-output channels only. Its
functionality, supported software and operation performance is identical to
that of the PCI-6308V, Hence no further reference to the PCI-6308 is outline
in this manual.
The PCI-6308A is the combination of the PCI-6308V with an 8-CH current
output extended board modeled EXP-8A. The EXP-8A board includes 8
precision voltage-to-current converters/transmitters, which converts voltage
output of PCI-6308V to a current source output. The EXP-8A is piggybacked
onto the PCI-6308V. Therefore, the PCI-6308A provides both voltage and
current outputs. The total number of analog output channel is still 8.
