The analyzer computes statistical power measurements using all samples in
the current time record. Each successive measurement adds additional
samples to the measurement. Pressing [

Changing [
does not restart the measurement. For example, if you measure peak
power and then select average power, the analyzer recomputes average
power using all samples from the peak power measurement. This lets you
view different statistics on the same data.
Important
Statistical power measurements operate on time data. By default, time data is
uncalibrated. Therefore, make sure you enable time-domain corrections as
done by step 1 in this procedure before making these measurements.
In this example, the peak
power of this signal will
be below this value
99.8% of the time.
