Excitation problems

Problem

The amplitude of the tuned frequency response falls well below a value of 0 decibels in the lower frequency range.

Excitation problems 1:

Solution

An unexpected, significant drop in amplitude is often due to insufficient excitation. Increase the excitation amplitude in the section Bode settings by either increasing the percentage threshold value or disabling the automatic calibration of the excitation and manually configuring a suitable value.
