optoanalysis.LeCroy package¶

optoanalysis.LeCroy.LeCroy module¶

class optoanalysis.LeCroy.LeCroy.HDO6104(address='152.78.194.16')[source]¶

Bases: object

Class for communicating with the Teledyne LeCroy Oscilloscope.

data(channel=1)[source]¶

Reads the raw input from the scope and interprets it returning the header information, time, voltage and raw integers read with the ADC.

Parameters:	channel : int channel number of read
Returns:	WAVEDESC : dict dictionary containing some properties of the time trace and oscilloscope settings extracted from the header file. x : ndarray The array of time values recorded by the oscilloscope y : ndarray The array of voltage values recorded by the oscilloscope integers : ndarray The array of raw integers recorded from the ADC and stored in the binary file

opc()[source]¶

Asks the oscilloscope if it is done processing data.

Returns:	IsDoneProcessing : bool returns False if oscilloscope is still busy, True is oscilloscope is done processing last commands.

raw(channel=1)[source]¶

Reads the raw input from the oscilloscope.

Parameters:	channel : int channel number of read
Returns:	rawData : bytes raw binary data read from the oscilloscope

waitOPC()[source]¶: Waits for a response from the oscilloscope indicating that processing is complete and it is ready to receive more commands. Function sleeps until the oscilloscope is ready.

optoanalysis.LeCroy.LeCroy.InterpretWaveform(raw, integersOnly=False, headersOnly=False, noTimeArray=False)[source]¶

Take the raw binary from a file saved from the LeCroy, read from a file using the 2 lines: with open(filename, “rb”) as file: raw = file.read() And extracts various properties of the saved time trace.

Parameters:

raw : bytes: Bytes object containing the binary contents of the saved raw/trc file
integersOnly : bool, optional: If True, only returns the unprocessed integers (read from the ADC) rather than the signal in volts. Defaults to False.
headersOnly : bool, optional: If True, only returns the file header. Defaults to False.
noTimeArray : bool, optional: If true returns timeStart, timeStop and timeStep and doesn’t create the time array

Returns:

WAVEDESC : dict: dictionary containing some properties of the time trace and oscilloscope settings extracted from the header file.
x : ndarray / tuple: The array of time values recorded by the oscilloscope or, if noTimeArray is True, returns a tuplef of (timeStart, timeStop, timeStep)
y : ndarray: The array of voltage values recorded by the oscilloscope
integers : ndarray: The array of raw integers recorded from the ADC and stored in the binary file
MissingData : bool: bool stating if any data was missing
