OutputRange (Data Acquisition Toolbox)

OutputRange specifies the range of the analog output hardware device. For many devices, this range is expressed in terms of gain and polarity. Therefore, if you set OutputRange to a particular value, then gain and/or polarity are automatically modified accordingly.

Hardware devices have a finite number of OutputRange values that can be set. If an OutputRange value is specified but does not match a valid value, then the closest supported value is automatically selected by the engine.

Since OutputRange can be set to a value that differs from the one specified, you should return the actual output range for each channel.

ActualRange = get(AO.Channel(index), 'OutputRange');

Alternatively, you can use the setverify function. This function sets the output range value and then returns the actual value set.

ActualRange = setverify(AO.Channel(index), 'OutputRange', Value)
