Calibrate conversion factor

Functions and script to calibrate the conversion factor of Alice.

qosst_alice.tools.calibrate_conversion_factor.DEFAULT_VOA_1_LOCATION: str = ''

Default value for the first VOA device.

qosst_alice.tools.calibrate_conversion_factor.DEFAULT_VOA_2_LOCATION: str = ''

Default value for the second VOA device.

qosst_alice.tools.calibrate_conversion_factor.DEFAULT_VOA_START_VALUE: float = 1.0

Default start value for the VOA.

qosst_alice.tools.calibrate_conversion_factor.DEFAULT_VOA_END_VALUE: float = 5.0

Default end value for the VOA.

qosst_alice.tools.calibrate_conversion_factor.DEFAULT_VOA_STEP_VALUE: float = 0.05

Default step value for the VOA.

class qosst_alice.tools.calibrate_conversion_factor.CalibrateConversionFactorData(pm1: ndarray, pm2: ndarray, conversion_factor: float)

Data container for he output of the calibration script of the conversion factor.

Parameters:

• pm1 (np.ndarray) – array of powers on the first powermeter.

• pm2 (np.ndarray) – array of powrs on the second powermeter.

• conversion_factor (float) – value of the conversion factor between the two powermeters.

qosst_alice.tools.calibrate_conversion_factor.calibration_conversion_factor(args: Namespace) → None

Estimate the conversion factor by taking the power at the output of Alice and the power usually measured by Alice.

Parameters:

args (argparse.Namespace) – the arguments, in particular the save.
