Normal
One of the marker types. It is used to measure the X (Frequency or Time) and Y
(Amplitude) values of a certain point on the trace. When selected, a marker with
the number of the current marker (such as “1”) appears on the trace.
Key Points:
 If no active marker exists currently, a marker will be enabled automatically at
the center frequency of the current trace.
 You can use the numeric keys, knob or direction keys to move the marker. The
