No description provided.

The driver narrowed root_instrument and instrument to the concrete
driver classes with an annotation plus a suppression, and worked around
pyvisa typing the return of read_binary_values and query_binary_values
as Sequence[float] regardless of the requested container. Spell both as
cast instead, which all three type checkers accept and which drops five
suppressions.

🚀 New features to boost your workflow:
  • ❄️ Test Analytics: Detect flaky tests, report on failures, and find test suite problems.

Add a pyvisa-sim yaml for the Infiniium and a test module covering the
type narrowing added to ``DSOTraceParam``: the ``root_instrument``
property, the ``setpoints`` property for channels and for FFT and
non-FFT functions, and the ``update_fft_setpoints`` guard.
