Saving traces

When performing an acquisition through the AcquisitionParameter using the measurement Loop, the returned data has already been processed from the measured traces. It can be desired to also store the raw traces, and this feature is provided by setting

>>> acquisition_parameter.save_traces = True

A single HDF5 file is created to store all the traces generated by the AcquisitionParameter during the entire measurement Loop. If a Loop contains multiple AcquisitionParameters with save_traces = True, a separate file is created for each one.

For a given DataSet generated by the loop, the traces can be loaded using

>>> dataset.load_traces()

which uses the python package h5py.

Note

Depending on the measurement performed, a traces HDF5 file can quickly become too large to fully load into the memory. h5py allows parts of the full array to be loaded using slicing, see their documentation for details.
