Calibration

[artkolisnyk]

Hello guys. Do you know if there is a way to perform microphone calibration via gRPC in way similar to NI MAX?

Hi @artkolisnyk,

You can use the Channel Calibration Wizard in NI MAX, save a task/global channel containing the calibration results, and load that task/global channel from Python and/or via gRPC. However, you can't call the Channel Calibration Wizard programmatically, via gRPC or any other API.

To programmatically perform a channel calibration over gRPC, you currently need to reimplement the channel calibration algorithm. This would involve acquiring various data points, then configuring a custom scale to use a table or polynomial scale to apply the appropriate calibration scaling.

Also, nidaqmx-python does not support the Channel Calibration properties such as Analog Input >> General Properties >> Channel Calibration >> Has Valid Calibration Information at this time. If that would be useful to you, please file a GitHub issue. Using these properties instead of a custom scale allows you to combine the calibration scaling with another custom scale.

Got it, thanks.
