All notable changes to Pulselib will be documented in this file.

[1.6.1] - 2022-12-06

Added

• start_times to measurement_description

Attention !!

• Digitizer trigger timing has been corrected for channel delays !!
• Digitizer RF source API has changed.

[1.5.1] - 2022-08-03

Added

• Added sequencer.plot()

Fixed

• Fixed looping t_off of add_HVI_marker
• Fixed plotting after mk_sequence

[1.5.0] - 2022-07-25

Added

• Support for Qblox modules: QCM and QRM
• Added sequencer.get_channel_data
• Added sequencer.set_acquisition
• Added sequencer.get_measurement_param with automatic upload/play and thresholding
• Added sequencer.get_measurement_results
• Added channel acquire(..., n_repeat= , interval= )

• Added digitizer configuring by M3202A_Uploader.

Changed

• Default channel offset is None to allow configuration outside of pulselib

Fixed

[1.4.0] - 2022-05-17

Changed

• Renamed Tektronix backend 'Tektronix_5014' after refactoring:

  • Use infinite looping when n_rep > 65535

Added

• Added sequencer.repetition_aligment to align the duration of the sequence with an external clock or signal frequency. (currently only implemented for Tektronix)
• Added argument reset_time to wait()
• Several pages of documentation (not finished yet..)

[1.3.5] - 2022-03-29

Fixed
