Apply amplitude fluctutations at a fixed rate #712

Open HGSilveri opened 4 months ago

HGSilveri commented 4 months ago

Now that I see it, the implementation is perhaps a bit weird, since in the case of a Sequence containing only one super-long pulse, the value of noise_base that will be applied will be the same all along - there will be no "fluctuation" actually. I would suggest to define a rate at which fluctuations should happen (and perhaps they should fluctuate at each ns ?), and sample them at each run (as it's done at the moment).

It seems that the dominant fluctuations in amplitude actually occur from shot to shot. As such, I propose we restrict the existent "amplitude fluctuation" to be a constant shift in the amplitude of a global channel over the entire sequence. If at some point we want to also introduce "intra-shot" fluctuations, we would require additional parameters for that.
