To assist in the measurement of noisy signals, a peak measurement function and an averaging function are available. When one of these options is selected the last five samples will be used for calculations. The result is displayed in the graph window. The user may also select a larger time span as basis for calculations from anywhere in the waterfall window.
Measure Peak and Average Values
Select the function you wish to use from the Options menu. A checkmark is shown to the left of the option selected and five samples are inverted in the waterfall window selected to indicate the number of samples used for the calculations.
If you wish to use a different number of samples in the calculation, place the mouse on the waterfall sample from which calculation should start, and hold and drag the mouse over as many samples as you want to use.
The marked samples will be color inverted, cursors will appear in the graph window and the graph display will show the average or peak value of the marked samples.
To disable peak or average measurement, uncheck it in the Options menu: the cursors will disappear, only one sample is marked in the waterfall window, and updating of the graph window will resume.
Examine Sample, Display Cursors
Click on the baudrate or the spectrum graph window to display the cursors, or click on the sample in the waterfall window that you wish to examine. Graph window updates will stop and a pair of cursors will appear. You may move the cursors along the x-axis in normal Windows fashion. The matching waterfall sample is marked with the time cursor.
Click on the graph window again to remove the cursors and resume graph window updates.
