Detailed Description

This logic module gathers data from wavemeter and the counter logic.

Constructor & Destructor Documentation

__init__()

def wavemeter_logger_logic.WavemeterLoggerLogic.__init__	(		self,
			config,
			kwargs
	)

Create WavemeterLoggerLogic object with connectors.

Parameters

dict	config: module configuration
dict	kwargs: optional parameters

Member Function Documentation

draw_figure()

def wavemeter_logger_logic.WavemeterLoggerLogic.draw_figure

(

self

)

Draw figure to save with data file.

Returns

: fig fig: a matplotlib figure object to be saved to file.

get_bins()

def wavemeter_logger_logic.WavemeterLoggerLogic.get_bins

(

self

)

Current number of bins in the spectrum.

Returns

int: current number of bins in the scan

get_fit_functions()

def wavemeter_logger_logic.WavemeterLoggerLogic.get_fit_functions

(

self

)

Return the names of all ocnfigured fit functions.

Returns

list(str): list of fit function names

get_max_wavelength()

def wavemeter_logger_logic.WavemeterLoggerLogic.get_max_wavelength

(

self

)

Current maximum wavelength of the scan.

Returns

float: current maximum wavelength

get_min_wavelength()

def wavemeter_logger_logic.WavemeterLoggerLogic.get_min_wavelength

(

self

)

Current minimum wavelength of the scan.

Returns

float: current minimum wavelength

nm_to_ghz()

def wavemeter_logger_logic.WavemeterLoggerLogic.nm_to_ghz	(		self,
			wavelength
	)

Convert wavelength to frequency.

Parameters

float

wavelength: vacuum wavelength

Returns

float: freequency

recalculate_histogram()

def wavemeter_logger_logic.WavemeterLoggerLogic.recalculate_histogram	(		self,
			bins = None,
			xmin = None,
			xmax = None
	)

Recalculate the current spectrum from raw data.

int bins: new number of bins

Parameters

float	xmin: new minimum wavelength
float	xmax: new maximum wavelength

save_data()

def wavemeter_logger_logic.WavemeterLoggerLogic.save_data	(		self,
			timestamp = None
	)

Save the counter trace data and writes it to a file.

Parameters

datetime

timestamp: timestamp passed from gui so that saved images match filenames of data. This will be removed when savelogic handles the image creation also.

Returns

int: error code (0:OK, -1:error)

start_scanning()

def wavemeter_logger_logic.WavemeterLoggerLogic.start_scanning	(		self,
			resume = False
	)

Prepare to start counting: zero variables, change state and start counting "loop".

Parameters

bool	resume: whether to resume measurement
