fix check no_of_samples

changed at row 204 from
if timebase_options.no_of_samples is not None and timebase_options.no_of_samples > max_samples_possible:
to
if timebase_options.no_of_samples is not None and timebase_options.no_of_samples > max_samples_possible.value:

the check to calculate timebase while requesting a fixed number of samples is not correct
