calix.common.adc_characterization.ADCCharacterization

class calix.common.adc_characterization.ADCCharacterization(test_values: Sequence[int], readout_pad: int = 0)

Bases: object

Use an external voltage source to determine the relationship between ADC values and voltages.

The external voltage source is set to a number of desired values and the ADC is read at these values.

Variables

• recording_time – Time to record at each voltage level.

• wait_before_measurement – Waiting time (in us) before the ADC samples are recorded at each setting of the external voltage.

__init__(test_values: Sequence[int], readout_pad: int = 0)

Parameters

• test_values – Values to set for the external voltage source.

• readout_pad – Pad at which the external voltage is applied.

Methods

__init__(test_values[, readout_pad])	param test_values Values to set for the external voltage source.
configure_parameters(builder, parameter)	Configure external voltage source.
prelude(connection)	param connection Connection to the chip to calibrate.
run(connection)	Perform measurement.

Attributes

Parameters

• builder – Builder to append configuring instructions.

• parameters – Voltage for external voltage source.

Returns

Builder with configuration instructions appended.
