Peak Computation (Peak)
The maximum value at each point of the computed data is determined, and the resulting values are used to
display the waveform. For each computation, the new computed value is compared with the past value, and the
larger value is kept.
3 sets of FFT data
The maximum values of each point
are displayed.
• The instrument normally performs scaling by using the computed data at the beginning (auto scaling).
When the amplitude of the averaged waveform changes significantly, use manual scaling.
• When you execute averaging, after measurement is stopped, computation cannot be restarted.
• If you measure an averaged waveform with auto scaling enabled, you cannot change the scaling by
switching to manual scaling after measurement has stopped. Changes to the scaling settings are applied
to the next measurement.
• If you change the computation conditions during averaging, the computed data up to that point is deleted,
and averaging starts over.
