Changelog

v3.0: Docs are overrated

Comprehensive documentation now available on read the docs, added more command line programme options, some function name changes without compatibility, and bug fixes.

v3.0.2 (2020-02-10)

  • Context manager compatibility (__enter__ and __exit__ functions implemented)

  • Adding the function get_active_channels to query the scope of its active channels

  • Adding verbose attribute

v3.0.1 (2019-10-31)

  • Some adaptation for using Infiniium oscilloscopes with limited functionality

  • Expanding the contents of the list_visa_devices table

  • Bugfix for ascii data processing (originating in v3.0.0)

v3.0.0 (2019-10-28)

  • Expanded command line programmes to take many more options:

    • Connection settings: visa_address, timeout

    • Acquiring settings: channels, acq_type

    • Transfer and storage settings: wav_format, num_points, filename, file_delimiter

  • Added Oscilloscope.generate_file_header() to generate file header with structure:

    <id>
<mode>,<averages>
<timestamp>
time,<chs>

    Now used by save_trace()

  • (No compatibility measures introduced): Camel case in function names is no more

  • getTrace -> get_trace

  • saveTrace -> save_trace

  • plotTrace -> plot_trace

  • and others

  • (No compatibility measures introduced): Oscilloscope.build_sourcesstring() -> Oscilloscope.determine_channels() and changed return sequence

  • (No compatibility measures introduced): module installed_commandline_funcs -> installed_cli_programmes

  • (No compatibility measures introduced): functions ending with _command_line() -> _cli()

  • Fixed issue when setting number of points to transfer

  • Fixed issue (hopefully) with sometimes getting wrong traces exported. Have now set communication to signed ints, and setting least significant bit first

  • Fixed issue where ASCii wave format would set zero time to the beginning of the trace

  • Wrote comprehensive documentation on read the docs

v2.1: May I have your address?

New command line programmes for listing visa devices and finding config

v2.1.0 (2019-10-18)

  • Added command line programme list_visa_devices to list the addresses of the VISA instruments available

  • Added command line programme path_of_config to show the path of config.py

  • Explicitly setting scope to transfer in unsigned ints when doing BYTE and WORD waveform formats

  • Added functions for setting oscilloscope to running and stopped, and for direct VISA command write and query

  • Changed dependency from visa to pyvisa (the package called visa on pypi is not pyvisa..!), and added tqdm dependency

  • (No compatibility measures introduced): get_n_traces now called get_num_traces

  • And minor cosmetic changes

v2.0: Labels for everyone

v2.0.1 (2019-09-13)

  • Cosmetic change in README, clarifying changelog for previous version

v2.0.0 (2019-08-29)

  • When using Oscilloscope.set_options_get_trace_save(), channels are now comma separated in the csv to provide channel headings according to the data columns. This is not directly compatible with previous versions as these had two lines of preamble in csvs, whereas it is now three (Instrument info, columns descriptions, date and time)

  • Added BYTE/WORD issue to README

v1.1: Need for speed

v1.1.1 (2019-08-14)

  • Logging gives elapsed time in milliseconds

  • Change in logging level for elapsed time

v1.1.0 (2019-04-04)

Extra command line programme, logging enabled, order of magnitude speed-up in data processing

  • Added command line programme for obtaining a given number of traces consecutively

  • Former debugging print is now directed to logging.debug()

  • Oscilloscope.process_data_binary() is approx an order of magnitude faster

  • Added license file

  • Changes in README

v1.0: Hello world

v1.0 (2019-03-07)

  • First release on pypi
