NanoVNA-Saver 3.8 pre division by 0

[PA3CCE]

This morning I started a fresh calibration in NanoVNA-Saver 0.3.8 pre, 1MHz to 2GHz, 10 Segm,ents, 401 datapoints, 100 Hz Bandwidth. The "short" caalibration went well, but while running the "open" calibration I got a "divide by "zero" errormessage. See screenshot and errormessage "calibration.txt".

When the sweep fails it returns a zero length array of data that causes a crash. The stack is shown in the calibration.txt.

Zero length of array is checked in newer versions
