N dB BW
Enable the N dB BW measurement or set the value of N dB. The N dB BW denotes the frequency
difference between two points that are located on both sides of the current marker and with N dB
fall (N Less than or equal to 0) or rise (N>0) in amplitude as shown in the figure on the next page.
When the measurement starts, the analyzer will search for the two points which are located at both
sides of the current point with N dB fall or rise in amplitude and display the frequency difference
between the two points in the active function area. "----" would be displayed if the search fails.
The parameters in the figure are shown as
