Fig.3.51 Mark menu (page 2)
If there is no marker on, the system will automatically set the normal marker to on. If there are some “On” markers,
the state of these markers will remain unchanged.
1) Normal Marker
After pressing “Mkr Normal” soft-key or pressing NORMAL key while no marker is set “On”, the normal marker
will appear on the screen. And at the same time the amplitude and frequency/time information of this marker will
be displayed on the up-right of the screen. When the span is set to zero, the wave display on the screen is a time
domain wave, so the abscissa is changed from frequency to time. The start time is zero and the stop time is equal to
sweep time. The displayed marker information is changed to time too.
The abscissa of the marker can be changed by three methods:
a. Press “Up/Down” cursor. The step change of this method is 1/10 of span.
b. Rotate the knob. The step change is 1/500 of the span.
c. Manually input the number user needed.
2) Delta Mark
After pressing this soft-key, two markers will appear on the screen. The start positions of these two markers are the
same. Rotating the knob, pressing the “Up/Down” cursor or manually inputting the frequency value can change the
position the second marker. The amplitude and frequency/time difference between two markers will be displayed
on the up-right of the screen. The main function of “Delta Mark” is to compare two signals.
