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
average noise level read at the frequency scale is normalized to 1
Hz bandwidth for noise power.
5.16.4 [Freq Count►]
Activate the frequency counter function and display the count
results in the upper right corner of the screen. The counter counts
only the signals that are displayed on the screen. The frequency
count also pops up an additional counter function for the soft menu,
including [Freq Count On Off ].
1) [Freq Count On Off]
Turn on or off the frequency counter mode. This function is invalid
when the trace signal generator is activated. The count value is
displayed in the upper right corner of the screen.
2) [Resolution]
Counter resolution is divided into 1 kHz, 100 Hz, 10 Hz, 1Hz.
Changing the counter resolution can change the counter accuracy.
The higher the resolution, the higher the counting accuracy.
3) [Return]
Return to the previous menu.
