Overview
The notch search function is used to obtain the bandwidth, center
frequency, cutoff points (high-frequency side and low-frequency side), Q,
and insertion loss of a trace based on the active marker position. The notch
search function starts from the left side of the active marker position, and
ends when points that meet the conditions are found.
The figure and the table below shows the definition of parameters obtained
by notch search function. The notch value in figure below must be specified
by the user.
