To Use Marker Math Functions

The three marker math functions—statistics, flatness, and RF filter
stats—perform certain mathematical calculations on the amplitude data
of user-defined trace segments.
For measurement channel 1, the trace segment is defined with markers 1
and 2; for measurement channel 2, the trace segment is defined with
markers 3 and 4. The marker math parameters are updated after each
sweep, as well as any time a marker is moved. Regular marker tracking
is not available with the marker math functions.
You cannot have marker math functions active at the same time as
marker search functions.
The marker statistics function measures a user-defined segment of the
measurement trace and calculates the following:
• frequency span
• mean amplitude
• standard deviation of the amplitude response
• peak-to-peak ripple
Limit testing may be performed on the statistical mean and peak-to-peak
ripple. See "To Use Marker Limit Functions" on page 4-32
information.
1. On measurement channel 1, press
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.)
