Using Markers
Using the Next Peak and Next Min Functions.
As explained previously, pressing ?%z -> Max and NW --3 Mn will
place a marker on the maximum and minimum points on the measurement
trace, respectively. You can search for the next highest or lowest point
using the Wxt Peak Right , Next Pssak Laft , %ext Mfa Right and
&vct M&I L&t keys.
A maximum (or minimum) point is detected whenever an amplitude
excursion greater than half of a division occurs. The half of a division
excursion requirement must be satisfied on both sides (left and right) of the
peak (or minimum). The maximum (or minimum) point must be >-60 dE3.
See Figure 4-4.
