Args:
name (str): Name of the measurement.
tdx (np.array): Time axis for the x axis of the measurement data. This can be multi-dimensional.
tdy (np.array): Time axis for the y axis of the measurement data. This can be multi-dimensional.
tdx (np.array): Time axis for the x axis of the measurement data. This can be multi-dimensional. Axis 0 are the different data sets (e.g. phase cycles).
tdy (np.array): Time axis for the y axis of the measurement data. This can be multi-dimensional. Axis 0 are the different data sets (e.g. phase cycles).
target_frequency (float): Target frequency of the measurement.
frequency_shift (float, optional): Frequency shift of the measurement. Defaults to 0.
IF_frequency (float, optional): Intermediate frequency of the measurement. Defaults to 0.
