class Acquisition(Operation):
"""
An operation representing data acquisition at the quantum-device abstraction layer.
An Acquisition must consist of (at least) an AcquisitionProtocol specifying how the
acquired signal is to be processed, and an AcquisitionChannel and AcquisitionIndex
specifying where the acquired data is to be stored in the RawDataset.
N.B. This class helps differentiate an acquisition operation from the regular
operations. This enables us to use
:func:`~.quantify_scheduler.schedules._visualization.pulse_diagram.plot_acquisition_operations`
to highlight acquisition pulses in the pulse diagrams.

class Trace(Acquisition):
"""
The Trace acquisition protocol measures a signal s(t).
Only processing performed is rescaling and adding
units based on a calibrated scale. Values are returned
as a raw trace (numpy array of float datatype). Length of
this array depends on the sampling rate of the acquisition
device.
.. important::
The exact duration of this operation, and the possible bin modes may depend on
the control hardware. Please consult your hardware vendor's :ref:`Reference
guide` for more information.
Parameters
----------
port
The acquisition port.
clock
The clock used to demodulate the acquisition.
duration
The acquisition duration in seconds.
acq_channel
The data channel in which the acquisition is stored, is by default 0.
Describes the "where" information of the measurement, which typically
corresponds to a device element idx.
acq_index
The data register in which the acquisition is stored, by default 0.
Describes the "when" information of the measurement, used to label or
tag individual measurements in a large circuit. Typically corresponds
to the setpoints of a schedule (e.g., tau in a T1 experiment).
bin_mode
Describes what is done when data is written to a memory location that already
contains values. Which bin mode can be used for Trace acquisitions may depend on
the hardware. ``BinMode.AVERAGE``, the default, works on most hardware. This bin
mode stores the weighted average value of the new result and the old values.
``BinMode.FIRST`` is used for hardware where only the result of the first
acquisition in a Schedule is stored, e.g. for a Trace acquisition with Qblox QTM
modules.
t0
The acquisition start time in seconds, by default 0.

class ThresholdedTriggerCount(Acquisition):
"""
Thresholded trigger counting acquisition protocol returning the comparison result with a
threshold.
If the number of triggers counted is less than the threshold, a 0 is returned, otherwise a 1.
The analog threshold for registering a single count is set in the hardware configuration.
.. important::
The exact duration of this operation, and the possible bin modes may depend on the control
hardware. Please consult your hardware vendor's :ref:`Reference guide` for more information.
Parameters
----------
port
The acquisition port.
clock
The clock used to demodulate the acquisition.
duration
The duration of the operation in seconds.
threshold
The threshold of the ThresholdedTriggerCount acquisition.
feedback_trigger_label
The label corresponding to the feedback trigger, which is mapped by the compiler to a
feedback trigger address on hardware, by default None.
Note: this label is merely used to link this acquisition together with a
ConditionalOperation. It does not affect the acquisition result.
feedback_trigger_condition
The comparison condition (greater-equal, less-than) for the ThresholdedTriggerCount
acquisition.
acq_channel
The data channel in which the acquisition is stored, by default 0. Describes the "where"
information of the measurement, which typically corresponds to a qubit idx.
acq_index
The data register in which the acquisition is stored, by default 0. Describes the "when"
information of the measurement, used to label or tag individual measurements in a large
circuit. Typically corresponds to the setpoints of a schedule (e.g., tau in a T1
experiment).
bin_mode
Describes what is done when data is written to a register that already contains a value.
Options are "append" which appends the result to the list or "average" which stores the
count value of the new result and the old register value, by default BinMode.APPEND.
t0
The acquisition start time in seconds, by default 0.
