What’s New in the SHFQC User Manual

SG Channels: 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).

SG Channels: Added ability for internal feedback to use multi-state discrimination data to enable reset of multi-level systems.

QA Channels: Added power-spectral-density (PSD) measurement capability to the spectroscopy mode. The PSD measurement gets controlled via the node tree branch /DEV*/QACHANNELS/*/SPECTROSCOPY/PSD.

QA Channels: Added node /DEV*/QACHANNELS/*/INPUT/ADCOVERRANGECOUNT, allowing users to independently monitor ADC overrange conditions.

Manual: Improved UI documentation. Added additional documentation on usage of internal feedback, playZero, and playHold.

SG Channels: Improved efficiency of playZero and playHold to use fewer assembly instructions.

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

LabOne: Improved support for alternative hardware components.

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

Outputs: Improved alignment between SG and QA channel outputs when triggered by the Internal Trigger.

Scope: Fixed a bug that caused a wrong effective scope delay at startup.

Outputs: Fixed a bug that caused overrange conditions during the ADC calibration at startup.

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.

LabOne: Added support for the SHFQC Qubit Controller, including full support in the LabOne UI.

SG Channel: Added new SG-channel sequencer command getFeedback that can retrieve ZSync data or qubit data from the QA channel.

SG Channel: Added ability of executeTableEntry to use variable arguments corresponding to qubit data received over ZSync or from the QA channel.

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

SG Channel: Added support for 16 sample waveforms with the command table.

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

SG Channel: Improved the speed with which the SG channel AWGs can be enabled.

QA Channel: Improved the maximal repetition rate, with which the QA readout can be started without missing triggers to 1/(440 ns).

QA Channel: Fixed a bug, where the error "The sigin ADC reported unexpected dataconverter errors!" was issued during an over range condition at the QA channel inputs.

ZSync/DIO: Added an internal trigger unit that allows the SG and QA channels to be synchronized with each other.

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 for the SG channels and qachanNseq or qachannelN_sequencer for the QA channel.

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*/QACHANNELS/*/GENERATOR/ELF/DATA node accepts raw data as 8-, 16-, and 64-bit integer vectors in addition to 32-bit words.
