In above example, the first data set (ID=0097) is a single frequency calibration
with 325 points at a primary frequency of 1.0 GHz. Horizontal movement ranges
from 0 to 5905 (Xmax), the vertical axis moves between 0 and 3210 (Ymax).
The second calibration (ID=106) is a single frequency cal at 3.5 GHz, but with
higher resolution (466 points).
Calibration #4 to #6 all have the same ID=128. This is a multi-frequency
calibration, primary frequency is 1.0GHz, with two secondary frequencies,
2.0GHz and 3.0GHz. All 3 calibration sets have the same number of points, Xmax
