Marker Function
N dB State
Enables or disables the N dB bandwidth measurement function.
Note: In the N db measurement state, if the current marker is disabled, then the N
dB BW measurement function is also disabled.
N dB Bandwidth
Sets the N dB value.
The N dB Bandwidth denotes the frequency difference between two points that are
located on both sides of the current marker and with N dB fall (N<0) or rise (N>0) in
amplitude, as shown in the figure below.
Figure 2-16 N dB Bandwidth Measurement
Remarks:
⚫ 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.
Once the two points are found, the analyzer will display the frequency difference
between the two points in the active function area. Once not found, "----" would
be displayed.
⚫ You can use the numeric keys, the knob, or arrow keys to modify the value of N.
