Entries from 0 dB to 80 dB are allowed; the resolution is 0.1 dB. The default setting for
the peak excursion is 6 dB.
For more information see chapter 7.4.1.4, "Searching for Signal Peaks" , on page 486.

Auto Max / Min Peak Search
If activated, a maximum or minimum peak search is performed automatically for
marker 1 after each sweep.
For spectrogram displays, define which frame the peak is to be searched in.
For EMI measurements, these functions are not available; use Automatic Peak Search
instead (see chapter 5.13.4.2, "EMI Final Measurement Configuration" , on page 302).
