[docs]class Pulsar:
"""
Class that provides the native API for the Pulsar. It provides methods to
control all functions and features provided by the Pulsar, like sequencer,
waveform and acquistion handling.
This class is build upon the :class:`~qblox_instruments.scpi.PulsarQcm`
and :class:`~qblox_instruments.scpi.PulsarQrm` classes through
composition. This allows us to create a generic native Pulsar class that
supports both Pulsar types, but only exposes the relevant interfaces,
while also keeping the SCPI classes automatically generated for fast
prototyping and development. On instantiation, this class probes the
connected device to see which Pulsar SCPI interface to support and adds
all respective attributes to this class. Afterwards, this class can be
used as if it inherits from it's respective Pulsar SCPI interface with all
features and functionality available.
Note that the bulk of the functionality of this class is contained in the
:mod:`~qblox_instruments.native.generic_func` module so that this
functionality can be shared between instruments.
