4.7.3 Marker Type
Marker supports 4 types: normal, differential, fixed, off. Depending on the type of cursor, the
reading and position of the cursor are also different when the trace is refreshed:
4.7.3.1
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.
⚫ 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 readouts of the
marker will be displayed at the upper right corner of the screen.
4.7.3.2
Delta
One of the marker types. It is used to measure the delta values of X (Frequency or Time) and Y
(Amplitude) between the reference point and a certain point on the trace. When selected, a pair of
markers appears on the trace: Fixed Related Marker (marked by a combination of the marker
number and letter “ + ”, such as “ 2+ ”) and the Delta Marker (marked by the “∆”, such as “ 1∆2 ”).
⚫ After the marker selects “Delta”, the original marker will become the delta measurement
marker, and the related marker of the incrementing sequence number will become the
reference “fixed” marker
⚫
The delta marker is in the "relative to" state, and its X-axis position can be changed; the
