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
andplayHold
. Added a tutorial on qubit tuneup. -
AWG: Improved efficiency of
playZero
andplayHold
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 fromchanNseq
orchannelN_sequencer
tosgchanNseq
orsgchannelN_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/
