TO get 1hz resolution with 101 points you need very narrow sweeps
so VNA-saver is likely the tool to do that.
Even with 10hz that only 1000hz sweep and likely not wide enough.
Also if you sweep too fast the crystal will ring and you get a tilted
result.
Without using software to splice multiple sweeps its a battle of
precision and number of possible points.
Even with a big VNA/PNA a lot of points (4096) at 1hz resolution
and a slow sweep (at least 40mS per point) was needed.
