Changelog for QCoDeS 0.15.0
The June 2020 release of QCoDeS. This release also includes all the changes mentioned in alpha release of June 2020 (Changelog for QCoDeS 0.15.0a1).
Group.instrumentare now all read only properties (#2031).
The public attributes
Group.get_cmdhave been removed (#2031).
It is now an error to supply get/set_cmd, if get/set_raw is not abstract (#2015).
The sweep parameters such as ‘sweep_mode’, ‘sweep_start’, ‘sweep_end’, ‘sweep_steps’ in Keysight B1520A driver is moved from class is moved from B1520A class to CVSweeper class (#2044).
New features are added to Keysight B1517A driver to allow IV staircase sweep measurements (#2028).
Various improvements are done on Keysight B1520A driver, such as, parsing correctly the wrong output floats (‘-0.-1’) from the instrument until new firmware release (#2023), improved testing (#2027), fixing spot measurement of capacitance checking for wrong impedance model, and working with ac_dc_volt_monitor=True (#2020), CVSweepMeasurements supports all impedance models (#2047).
The measurement status are added to current and voltage parameters of B1517A driver (#2051).
Added a method to obtain the measurement status summary of IV and CV Sweep measurements (#2050).
The get functionality for sweep_auto_abort and post_sweep_auto_abort parameters is added in Keysight B1517A and B1520A driver (#2049).
The error handling of Keysight B1500 driver is improved. Now each time a parameter is set the instruments queries for the error and throws exception is an error is received (#2041).
Now on_off_val_mapping is used instead of a custom parser in Agilent E8527D (#2030).
The parameter limits are added for the R&S ZNB-40 VNA R&S (#2029).
Add a few system functions to the Keithley 2450 driver (#2052)
The DelegateParameter is now allowed to change source and also support a None source (#2005).
The GroupParameter now correctly update their cache when a single parameter in the group has been set or captured (#2031).
The GroupParameter now correctly implements mappings between
Snapshot_base introduce new update=None, and use cache in parameter’s snapshot_base (#1833).
Now initial cache value can be set to the Parameter using kwarg
The snapshots of stations and instruments can also be diffed now using diff_param_values (#2021).
Under the hood:
New lines are now handled correctly on windows (#2026).
Parameterclass, the gettable/settable have become read only property (#2024).
Parameter cache.get is refactored to make the logic a bit more clear. Its functionality remains the same (#2008).
The loop data location in channels test is changed for pytest-xdist to work (#2010).
Added new dependency: “typing_extensions” (#2048)
