PCI-MIO-16E-1, PCI-MIO-16E-4, and PCI-6071E
These boards supply two channels of analog output voltage at the I/O
connector. The reference and range for the analog output circuitry is
software selectable. The reference can be either internal or external,
whereas the range can be either bipolar or unipolar.
PCI-MIO-16XE-10 and PCI-6031E
These boards supply two channels of analog output voltage at the I/O
connector. The range is software-selectable between unipolar (0 to
10 V) and bipolar (+10 V).
PCI-MIO-16XE-50
This board supplies two channels of analog output voltage at the I/O
connector. The range is fixed at bipolar ±10 V.
PCI-MIO-16E-1, PCI-MIO-16E-4, and PCI-6071E
You can connect each D/A converter (DAC) to these PCI E Series
boards' internal reference of 10 V or to the external reference signal
connected to the external reference (EXTREF) pin on the I/O connector.
This signal applied to EXTREF should be within ±11 V. You do not
need to configure both channels for the same mode.
PCI-MIO-16E-1, PCI-MIO-16E-4, and PCI-6071E
You can configure each analog output channel for either unipolar or
bipolar output. A unipolar configuration has a range of 0 to V
analog output. A bipolar configuration has a range of –V
