Gets or sets the expected thermal operating range of the instrument from the self-calibration temperature, in degrees Celsius, returned from GetDeviceTemperature.

Syntax

Namespace: NationalInstruments.ModularInstruments.NIRfsa

public double ThermalCorrectionHeadroomRange { get; set; }

Remarks

The default value for the PXIe-5830/5831/5832 is 5. The default value for the PXIe-5840 is 10.

For example, if this property is set to 5.0, and the device is self-calibrated at 35 degrees Celsius, then you can expect to run the device from 30 degrees Celsius to 40 degrees Celsius with corrected accuracy and no overflows. Setting this property with a smaller value can result in improved dynamic range, but you must ensure thermal stability while the instrument is running. Operating the instrument outside of the specified range may cause degraded performance and ADC or DSP overflows.

Exceptions

TypeDescription
System.ObjectDisposedException

The ThermalCorrectionHeadroomRange property was accessed after the associated NIRfsa object was disposed.
