Specifies whether the hardware automatically selects the best range to measure the signal. Note the highest range the algorithm uses is dependent on the corresponding limit range property. The algorithm the hardware uses can be controlled using the NIDCPOWER_ATTR_AUTORANGE_APERTURE_TIME_MODE attribute.

Specifies whether the aperture time used for the measurement autorange algorithm is determined automatically or customized using the NIDCPOWER_ATTR_AUTORANGE_MINIMUM_APERTURE_TIME attribute.

Specifies the algorithm the hardware uses for measurement autoranging.

Balances between settling time and maximum measurement time by specifying the maximum time delay between when a range change occurs and when measurements resume.

Specifies the measurement autorange aperture time used for the measurement autorange algorithm. The aperture time is specified in the units set by the NIDCPOWER_ATTR_AUTORANGE_MINIMUM_APERTURE_TIME_UNITS attribute. This value will typically be smaller than the aperture time used for measurements.

Specifies the units of the NIDCPOWER_ATTR_AUTORANGE_MINIMUM_APERTURE_TIME attribute.

Limiting the lowest range used during autoranging can improve the speed of the autoranging algorithm and minimize frequent and unpredictable range changes for noisy signals. The maximum range used is the range that includes the value specified in the compliance limit attribute, NIDCPOWER_ATTR_VOLTAGE_LIMIT_RANGE attribute or NIDCPOWER_ATTR_CURRENT_LIMIT_RANGE attribute, depending on the selected NIDCPOWER_ATTR_OUTPUT_FUNCTION.

Specifies thresholds used during autoranging to determine when range changing occurs.

Determines the relative weighting of samples in a measurement.

Specifies the number of samples that the active channel measurement buffer can hold.

Specifies when the measure unit should acquire measurements. Unless this attribute is configured to NIDCPOWER_VAL_ON_MEASURE_TRIGGER, the NIDCPOWER_ATTR_MEASURE_TRIGGER_TYPE attribute is ignored.

Specifies whether the measurement returned from any measurement call starts with a new measurement call (VI_TRUE) or returns a measurement that has already begun or completed(VI_FALSE).
