Using Instrument Functions
Using Markers
To Use Marker Flatness
The marker flatness search function measures a user-defined segment of the
measurement trace and calculates the following:
0
frequency span
a
gain
0
slope
0
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
“To
Use
Marker Limit Functions,’ later in this chapter for information.
1. On measurement channel 1 press
[MARKER)
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.)
3. Figure 4-13 shows a
deEned
trace segment. Notice the marker readout in
the upper right corner of the display.
