3.3.9.8 [Frequency marker function
Enter soft menu about frequency marker functions.
3.3.9.9 [Functions off]
Disable frequency marker measurement functions.
3.3.9.10 [NdB On Off]
Enable N dB bandwidth measurement function. NdB
bandwidth means frequency difference between two points
which are obtained by current marker frequency point
descending (N<0) NdB amplitude to the left and to the right,
or ascending N dB amplitude (N>0) upward.
Notes:
After you start measuring, firstly search two frequency
points which differ by N dB amplitude from current marker
frequency point to the left and right. If it is found,
frequency difference between them is displayed in active
function area.
You can use number keys to change the value of N; the
value of N defaults to 3.

3.3.9.11 [Frequency marker noise On Off]
]
Enable or disable frequency marker noise function. As for
selected marker, perform function of marking function, and
then read noise power density. When it is on, average
noise level read from frequency marker is noise power
normalized as 1Hz bandwidth.
3.3.9.12 [ Frequency counting ]
Enter soft menu of frequency counting.
3.3.9.13 [Frequency counting On Off]
Frequency of tested signal is more accurate if frequency
counting function is on.
3.3.9.14 [Resolution bandwidth]
Resolution of counter respectively is 1kHz, 100Hz, 10Hz,
and 1Hz. Accuracy of counter can be changed by changing
resolution of counter. Th higher the resolution is, the higher
the counting accuracy is.
3.3.9.15 [Frequency marker
Soft menus about frequency marker function pop up. Use
values of current marker to set instrument's other system
