It depends on how different the results are. Remember, the FW interpolates
between measured and stored cal values. Saver can be configured with 1001
points so the cal. sampling is much finer than a cal. on the native NANOVNA
(without SAVER).
***
Saver can do unlimited (in theory) number of points. It will just do
the required points
in segments. For H4 that would be X times 401 points to get to your desired
number of points.
Word of warning: Saver is a Python single thread software, after a certain
number of points it becomes
time consuming to process more that ~5K points on a single CPU core.
Again, using SAVER, there is the option to use considerably more points for
calibratioin: Native is 401 points, SAVER allows up to 1001 points. So
extrapolation between measured points using the two calibrations will be
coarser with the native VNA cal than with the SAVER cal.
Just avoid extrapolation: use the same frequency span when measuring as you
did when you calibrated ...
