This is for extreme precision electrical measurements needed for subtractive analysis so tiny details do count, in this case I need to have precision positioning of the pulse to reflect the DUT's transfer function (including any time-of-flight etc) fully "as is".
First question: When doing sweep imports (or even in the general case), does setting "t=0 at IR start" in the measurements panel guarantee that no sub-sample shifting is applied?
If so, wouldn't it be better to have an unlinked selection for the import dialog, to avoid the hidden dependency (took me days to figure it out)?
Second question: for the same reason of avoiding (hidden/uncontrolled) sub-sample shifts, how can a thusly imported IR be shifted by an *exact* integer sample multiple? I found that the empirical "IR start" often has some +-1 sample variation even for almost (99.99%) identical import data and I want to compensate that before applying windows. Using "t=0 at cursor" doesn't seem to be useful as the cursor cannot be set on an exact sample as far as I can see, so maybe a future "shift N samples" additional option for positioning, with N required to be an integer?
