What’s New in the SHFSG User Manual

Release 23.02

Release date: 28-Feb-2023

  • AWG: Extended functionality of resetOscPhase to able to reset the phase of the digital mixer (e.g. to enable reproducible phase setting when using the LF path).

  • AWG: Added a model to reliably predict feedback latency

  • AWG: Improved support for alternative hardware components.

  • AWG: Added ability for the device to prevent LabOne changes that are incompatible with the device hardware.

  • Manual: Added additional documentation on playZero and playHold. Added a tutorial on qubit tuneup.

  • AWG: Improved efficiency of playZero and playHold to use fewer assembly instructions.

  • Output: Improved timing jitter of output when triggering an SG channel over ZSync.

  • ZSync/DIO: Fixed a bug that caused the DIO interface to behave wrongly when switching between LVCMOS and LVDS outputs in non-manual mode.

  • LabOne: Fixed the value of legacy node /DEV*/CLOCKBASE for SHF devices. To have always the correct value, use the device node /DEV*/SYSTEM/PROPERTIES/TIMEBASE instead.

Release 22.08

Release date: 31-Aug-2022

  • AWG: Added support for 16 sample waveforms with the command table.

  • AWG: Added a new sequencer command playHold to allow the AWG to hold waveform and marker data for a specified number of samples.

  • AWG: Added ability of executeTableEntry to use variable arguments corresponding to qubit data received over ZSync.

  • AWG: Fixed a bug in which the command table always required a waveform to make parameter changes.

  • AWG: Improved the speed with which the AWGs can be enabled.

  • LabOne: Added waveform and marker delay settings in the Digital Modulation and DIO Tabs, respectively.

  • ZSync/DIO /DEV*/SGCHANNELS/*/AWG/ELF/DATA node accepts raw data as 8-, 16-, and 64-bit integer vectors in addition to 32-bit words.

  • ZSync/DIO /DEV*/DIOS/0/MODE node changed keyword arguments to enable control of DIO values by the sequencer from chanNseq or channelN_sequencer to sgchanNseq or sgchannelN_sequencer.

Release 22.02

Release date: 28-Feb-2022

Highlights:

  • Manual: Added new tutorials to the User Manual: Basic Sine Generation, Basic Waveform Playback, Triggering and Synchronization, Digital Modulation, Using the Python API, and Pulse-level Sequencing with the Command Table.

  • Manual: Added LabOne UI descriptions for the Digital Modulation and DIO Tabs to the User Manual.

  • AWG: Added support for fast sequencer-based IF sweeps via the SeqC commands configFreqSweep(), setSweepStep(), and setOscFreq().

  • AWG: Added support for conditional triggering over DIO via SeqC commands: setDIO(), getDIO(), waitDIOTrigger(), getDIOTriggered(), playWaveDIO().

  • AWG: Improved playWaveZSync() and getZSyncData() SeqC commands for fast feedback with PQSC.

  • AWG: Added ability for each sequencer to read data from either ZSync or DIO.

  • AWG: Added a built-in waiting time of wait(3) to the resetOscPhase() command, to prevent the oscillator from resetting during waveform playback.

  • AWG: Added support for waitSineOscPhase() SeqC command.

  • AWG: Fixed bug in which using too many triggers back to back would cause unpredictable waveform playback.

  • LabOne: Added support for the SHFSG in zhinst-deviceutils in the Python API, to improve user programming experience.

  • LabOne: Improved QCoDeS and Labber drivers and zhinst-toolkit to offer support of the SHFSG.

  • LabOne: Added low-frequency path control to the Output Tab in the LabOne UI. Updated documentation in the User Manual accordingly.

  • Outputs: Added ability to set the center frequency when using the low-frequency path. Accepted values: 0 - 2 GHz.

  • Outputs: Marker and trigger outputs adjusted to be aligned with the RF output by default.

  • Outputs: Default values of sine generator, AWG gain settings, and command table amplitude settings updated to automatically generate the upper sideband.

  • Outputs: Replaced the two AWG output amplitude settings with a single global amplitude setting. Default value is 0.5 to prevent saturating the DAC.

  • ZSync/DIO: Improved ZSync link stability.

  • ZSync/DIO: Fixed bug in which DIO outputs could not be set properly.

  • ZSync/DIO: Added the Real-Time Logger that logs history of incoming ZSync and DIO messages at /DEV*/SGCHANNELS/*/AWG/RTLOGGER/

Release 21.08
