Using Markers
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 dehned with markers 1 and
2; for measurement channel 2, the trace segment is deEned 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.
NOTE
You cannot have marker math functions active at the same time as marker search functions.

Statistics
The marker statistics function measures a user-dehned segment of the
measurement trace and calculates the following:
0 frequency span
l mean amplitude
l standard deviation of the amplitude response
0 peak-to-peak ripple
Limit testing may be performed on the statistical mean and peak-to-peak
ripple. See “lb Use Marker Limit Functions,” later in this chapter for
information.
1. On measurement channel 1 press @iEKE@ and set markers 1 and 2
to dehne 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 ?fa~k~ Functions Marker Pfath Stglti#As .
