What’s New in the SHFQA User Manual

Release 21.08

Release date: 27-Aug-2021

  • Sweeper: Added a feature to realize pulsed spectroscopy.

  • DIO: Enabled full DIO support. Added new node /DEV…​/DIOS/0/MODE to select mode, and introduced the following SeqC commands: setDIO(), getDIO(), waitDIOTrigger(), and getDIOTriggered().

  • Sequencer: Modified the behaviour of the startQA() SeqC command: The "trigger" argument now controls the trigger signal instead of the marker output.

  • Firmware Update: Firmware can now be updated via USB.

  • User Manual: Added tutorials for spectroscopy and qubit readout measurement.

  • LabOne GUI: Added Readout Pulse Generator Sequencer tab.

  • LabOne GUI: Added Quantum Analyzer Result Logger tab.

  • LabOne API: Moved Python API examples to GitHub, https://github.com/zhinst/labone-api-examples.

  • LabOne API: Added EnvelopeConfig in zhinst.utils.shf_sweeper for configuring the envelope for pulsed spectroscopy.

  • LabOne API: Renamed pointwise to sequential, sweepwise to cyclic, dwell_time to integration_time and num_samples to num_averages in zhinst.utils.shf_sweeper.

  • Added new nodes to select either "cyclic" or "sequential" averaging of results: /DEV…​/QACHANNELS/…​/READOUT/RESULT/MODE and DEV…​/QACHANNELS/…​/SPECTROSCOPY/RESULT/MODE.

  • LabOne API: Added a new node /DEV…​/SCOPES/0/SINGLE to switch between single-shot and continuous mode, only single-shot is available in this release (patch release).

  • LabOne API: Added new nodes
    /DEV…​/QACHANNELS/n/SPECTROSCOPY/ENVELOPE/…​ to enable multiplication of the oscillator signal with a complex envelope for pulsed spectroscopy.

  • LabOne API: Renamed /DEV…​/QACHANNELS/n/READOUT/RESULT/…​ to /DEV…​/QACHANNELS/n/SPECTROSCOPY/RESULT/…​.

  • LabOne API: Renamed
    /DEV…​/RAW/QACHANNELS/n/SPECTROSCOPY/TRIGGER/CHANNEL to
    /DEV…​/QACHANNELS/n/SPECTROSCOPY/TRIGGER/CHANNEL.

  • LabOne API: Renamed /DEV…​/SYSTEM/SWTRIGGER/…​ to
    /DEV…​/SYSTEM/SWTRIGGERS/…​.

  • LabOne API: Removed SEQUENCER/ from /DEV…​/QACHANNELS/n/GENERATOR/SEQUENCER/{AUXTRIGGERS/…​, DIO/…​, ELF/…​, ENABLE, SINGLE, READY, RESET}.

  • LabOne API: Removed the node /DEV…​/QACHANNELS/…​/READOUT/RESULT/RESET. Instead, a running measurement can now be stopped by writing 0 to the node /DEV…​/QACHANNELS/…​/READOUT/RESULT/ENABLE.
