Using the [Marker Function] hardkey, the analyzer lets you set the peak
percent and then display peak, average, or peak-to-average statistical power
for these configurations (otherwise the statistical softkeys are inactive):
l
The instrument mode is not Scalar.
l
The measurement contains time-domain data (x-axis is time).
The analyzer computes statistical power measurements using all samples in
the current time record. Each successive measurement adds additional
samples to the measurement. Pressing [
Measurement Restart] or changing most
parameters under the MEASUREMENT keygroup restarts the measurement.
The [
num samples] softkey displays the number of samples used in the
measurement.
Changing [
peak percent] or selecting a different statistical power computation
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.
