AT-MIO-16E-1, AT-MIO-16E-2, AT-MIO-64E-3, AT-MIO-16E-10, and
AT-MIO-16DE-10
The AT E Series devices supply two channels of AO voltage at the I/O
connector. You can select the reference and range for the AO circuitry
through software. The reference can be either internal or external, whereas
the range can be either bipolar or unipolar.
AT-MIO-16XE-50
The AT-MIO-16XE-50 supplies two channels of AO voltage at the I/O
connector. The range is fixed at bipolar ±10 V.
AT-MIO-16XE-10
The AT-MIO-16XE-10 supplies two channels of AO voltage at the I/O
connector. The range is software selectable between unipolar (0 to 10 V)
and bipolar (+10 V).
AT-MIO-16E-1, AT-MIO-16E-2, AT-MIO-64E-3, AT-MIO-16E-10, and
AT-MIO-16DE-10 only
You can connect each D/A converter (DAC) to the AT E Series device
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 between –10 and +10 V. You do not need to
configure both channels for the same mode.
AT-MIO-16E-1, AT-MIO-16E-2, AT-MIO-64E-3, AT-MIO-16E-10, and
AT-MIO-16DE-10 only
You can configure each AO channel for either unipolar or bipolar output.
A unipolar configuration has a range of 0 to V
configuration has a range of –V
reference used by the DACs in the AO circuitry and can be either the
+10 V onboard reference or an externally supplied reference between
–10 and +10 V. You do not need to configure both channels for the same
range.
