Meas Off (Spectrum Analyzer) Measurement
Example
Key Path
Average For each display point (interval) on the trace, Average detection displays the
power average (RMS) of the amplitude within the frequency interval represented by that
display point.
The most accurate averaged amplitude measurement will be made when you have at least
8 samples in each display point. Annotation will appear on the display when the current
instrument settings have reduced the number of samples/display point to less than 8.
"<8 Smpl/Pt" will be displayed until the instrument settings change so that the number of
samples increases.
The Average detector is very good for measuring noise or noise-like signals. For example,
an occupied power measurement will be more accurate using the Average detector than the
Sample detector. The Average detector is not recommended for measuring CW signals
because it can under represent the signal power that is best measured using the Peak
detector.

Clear Trace
Clears the selected trace. Does not affect the state of any function or variable in the box.
Loads minimum trace value into all of the points in the selected trace, unless the trace is
Min Hold
in in which case it loads maximum trace value. Does so even if Update is Off.
