class nqrduck_autotm.model.AutoTMModel(*args: Any, **kwargs: Any)

add_data_point(frequency: float, return_loss: float, phase: float) → None

Add a data point to the model. These data points are our intermediate data points read in via the serial connection. They will be saved in the according properties later on.

add_saved_position(frequency: float, tuning_position: int, matching_position: int) → None

Add a saved position to the model.

available_devices_changed

alias of list

clear_data_points() → None

Clear all data points from the model.

data_points_changed

alias of list

delete_saved_position(position: SavedPosition) → None

Delete a saved position from the model.

property frequency_sweep_end

The timestamp for when the frequency sweep has been ended. This is used for timing of the frequency sweep.

property frequency_sweep_start

The timestamp for when the frequency sweep has been started. This is used for timing of the frequency sweep.

init_load_calibration()

This method is called when a frequency sweep has been started for a load calibration in this way the module knows that the next data points are for a load calibration.

init_open_calibration()

This method is called when a frequency sweep has been started for an open calibration in this way the module knows that the next data points are for an open calibration.

init_short_calibration()

This method is called when a frequency sweep has been started for a short calibration in this way the module knows that the next data points are for a short calibration.

property measurement

The measurement property is used to store the current measurement. This is the measurement that is shown in the main S11 plot

saved_positions_changed

alias of list

property serial

The serial property is used to store the current serial connection.

serial_data_received

alias of str

class nqrduck_autotm.model.ElectricalLookupTable(start_frequency: float, stop_frequency: float, frequency_step: float)

add_voltages(tuning_voltage: float, matching_voltage: float) → None

Add a tuning and matching voltage for the last started frequency to the lookup table.

Parameters:

tuning_voltage (float) – The tuning voltage for the given frequency.

matching_voltage (float): The matching voltage for the given frequency.

get_next_frequency() → float

This method returns the next frequency for which the tuning and matching voltage is not yet set.

Returns:

The next frequency for which the tuning and matching voltage is not yet set.

Return type:

float

get_voltages(frequency: float) → tuple

Get the tuning and matching voltage for the given frequency.

Parameters:

frequency (float) – The frequency for which the tuning and matching voltage should be returned.

Returns:

The tuning and matching voltage for the given frequency.

Return type:

tuple

init_voltages() → None

Initialize the lookup table with default values.

is_incomplete() → bool

This method returns True if the lookup table is incomplete, i.e. if there are frequencies for which no the tuning or matching voltage is none.

Returns:

True if the lookup table is incomplete, False otherwise.

Return type:

bool

class nqrduck_autotm.model.LookupTable(start_frequency: float, stop_frequency: float, frequency_step: float)
