Analog Output

♦AT-MIO-16E-1,AT-MIO-16E-2, AT-MIO-64E-3,AT-MIO-16E-10, and

AT-MIO-16DE-10

The ATE Series devices supply two channels of AO voltage at the I/O

connector.You can select the reference and range for the AOcircuitry

throughsoftware. 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-50supplies 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-10supplies two channels of AOvoltage 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-10only

Youcan connect each D/A converter (DAC)to the AT E Series device

internalreference of10 V or to the externalreference signal connected

to theexternal reference (EXTREF) pin on the I/O connector. This signal

appliedto EXTREF should be between –10 and+10 V. Youdo not need to

configureboth 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-10only

Youcan configure each AO channel for either unipolar or bipolar output.

A unipolar configuration has ar ange of 0 to Vref atthe AO.A bipolar

configurationhas a range o f –Vref to +Vref at the AO.Vref is the voltage

reference used bythe DACs in the AO circuitry and can be either the

+10 Vonboard reference or an externally supplied reference between

–10 and +10 V.Youdo not need to configure both channels for the same

range.
