RigolWFM.channel Module

Class structure and methods for an oscilloscope channel.

The idea is to collect all the relevant information from all the Rigol scope waveforms into a single structure that can be handled in a uniform and consistent manner.

Specifically this lets one do:

channel.times   : numpy array of signal times
channel.volts   : numpy array of signal voltages

or the stringification method to describe a channel:

print(channel)

Functions

`best_scale`(number)	Scale and units for a number with proper prefix.
`engineering_string`(number, n_digits)	Format number with proper prefix.

Classes

`Channel`(w, channel_number, scope[, selected])	Base class for a single channel.
`Enum`(value[, names, module, qualname, type, ...])	Create a collection of name/value pairs.
`UnitEnum`(value[, names, module, qualname, ...])	Enumerated units for scopes without them.

RigolWFM.wfm Module

Extract signals or description from Rigol 1000E Oscilloscope waveform file.

Example

>>> import RigolWFM.wfm as rigol
>>> waveform = rigol.Wfm.from_file("file_name.wfm", 'E')
>>> description = waveform.describe()
>>> print(description)

Functions

valid_scope_list()

List all the oscilloscope types.

Classes

`Channel_Not_In_WFM_Error`	The channel is not in the .wfm file.
`Invalid_URL`	Cannot use this URL.
`Parse_WFM_Error`	Generic Parse Error.
`Read_WFM_Error`	Generic Read Error.
`Unknown_Scope_Error`	Not one of the listed Rigol oscilloscopes.
`Wfm`(file_name)	Class with parsed data from a .wfm file.
`Write_WAV_Error`	Something went wrong while writing the .wave file.

RigolWFM.wfmconvert Module

Command line utility to convert Rigol .wfm files.

Examples:

prompt> wfmconvert E info DS1102E-A.wfm

prompt> wfmconvert E csv DS1102E-A.wfm

prompt> wfmconvert E wav DS1102E-A.wfm

Functions

`csv`(args, scope_data, infile)	Create a file with comma separated values.
`info`(args, scope_data, infile)	Create a string that describes content of .wfm file.
`main`()	Parse console command line arguments.
`sigrok`(args, scope_data, infile)	Create a Sigrok (.sr) file.
`vcsv`(args, scope_data, infile)	Create a file with comma separated values (full volts).
`wav`(args, scope_data, infile)	Create an audible .wav file for use in LTspice.
