Oh believe me I know about samples and windowing. It's annoying as crap
Hence why I asked the question.
As for the 3 million/min... why do you make me do math? I hate math! so you'd be sampling at 48khz unless you wish to avoid windowing then you'd need to sample at 96khz. Is the timing sensor hall or optical? (I'm trying to estimate the sensor error to guesstimate the perturbed error)
so your calibration uncertainty is 0.04% which ain't bad. If you can nail down the timing uncertainty it will be easy enough to get an uncertainty plot for the pressure distribution.
