Marker Function

Executes specific marker soft menu.

5.16.1 [Function Off]

Turn off marker measurement function.

5.16.2 [NdB On Off]

Enables the N dB BW measurement or sets the value of N. The N

dB BW denotes the frequency difference between points that are

located on both sides of the current marker while the amplitude

falls off (N<0) or rises (N>0) N dB separately,

Key points:

 When the measurement starts, the analyzer will search the

two points which are located at both sides of the current point

and are N dB amplitudes smaller or greater than the current

point, and display the frequency difference between the two

points.

 You can use the numeric keys, knob or direction keys to

modify the value of N, 3 at default.

5.16.3 [Marker Noise On Off]

Turn on or off the frequency noise function. The function of marking

noise is applied to the selected cursor, and then the noise Power

Spectral Density at the cursor is read. When turned on, the
