Steve,
I experimented with this a lot in developing the software. The limiting
factor is the speed of the AGC. If I run the sweep faster, the AGC does not
change quickly enough to give any decent resolution. The program has a loop
that goes ike this:
1) Set a frequency
2) read S meter
3) plot a point on the graph
4) Go to step 1
If you do this too fast, the returned S meter reading does not change enough
from the previous reading for good resolution. I hope this explanation is
clear.
