Flatness
The marker flatness search function measures a user-defined segment of
the measurement trace and calculates the following:
• frequency span
• gain
• slope
• flatness
The analyzer calculates flatness by drawing a straight line between the
markers. A maximum vertical deviation from this line is computed for
each measurement point. Flatness is the magnitude difference of the
maximum and minimum calculated deviations from the straight line.
Limit testing may be performed on the flatness parameter. See
Marker Limit Functions” on page 4-32
1. On measurement channel 1, press
and set markers 1 and
2 to define the beginning and end of the trace segment that you want
to measure. (When using measurement channel 2, use markers 3 and
4 to define the trace segment.)
2. Press
