10. Cycle Stdev : Standard deviation of all data values in the first cycle
11. Rms : Root mean square of all data values.
12. Cycle RMS : Root mean square of all data values in the first cycle.
13. Median : Value at which 50% of the measurements are above and 50% are below.
14. Cycle Median : Median of the first cycle.
15. Overshoot (FOV and ROV) : Overshoot is distortion that follows a major edge transition expressed as a percentage
of Amplitude. ROV means rising edge overshoot and FOV means falling edge overshoot.

Preshoot (FPRE and RPRE)
: Preshoot is distortion that precedes a major edge transition expressed as a percentage
of Amplitude. The X cursors show which edge is being measured (edge closest to the trigger reference point).

Level@X
: The voltage value between the trigger point and the vertical position of the channel
