Making Measurements
Using Markers
To Calculate the Statistics of the Measurement Data This function calculates the mean, standard deviation, and peak-to-peak values of the
section of the displayed trace between the active marker and the delta reference. If there is
no delta reference, the analyzer calculates the statistics for the entire trace.
1. Move marker 1 to any point that you want to reference:
• Turn the front panel knob.
OR
• Enter the frequency value on the numeric keypad.
2. Press to make marker 1 a reference marker.
3. Press and move marker 2 to any position that you want to measure in
reference to marker 1.
4. Press to calculate and view the
mean, standard deviation, and peak-to-peak values of the section of the measurement
data between the active marker and the delta reference marker.
An application for this feature is to find the peak-to-peak value of passband ripple
without searching separately for the maximum and minimum values.
If you are viewing a measurement in the polar or Smith Chart format, the analyzer
calculates the statistics using the first value of the complex pair (magnitude, real part,
resistance, or conductance).
