If no activated cursor at the current, then activate a cursor at the center frequency of the current trace.
The reading of the current cursor will display on the upper right of the screen.
The resolution of X-axis (time or frequency) reading is related to the sweep span, which can be reduced
to achieve higher reading resolution.
2. Delta
△
:
Used to measure the difference between "reference point" and a "point on the trace": X (frequency or time)
and Y (amplitude) values.
After selecting "Difference", a pair of cursors will appear on the trace: the reference cursor (marked with
"×") and the difference cursor (marked with "
△
")
3. Fixed: After selecting "fixed" cursor, set the X and Y values of the cursor directly or indirectly, their
positions remain unchanged. Y value does not change with the trace. The fixed cursor is generally used
as the reference cursor of the difference cursor, and the fixed cursor is marked with "×".
4. Close: Turn off the selected cursor, the cursor information displayed on the screen and the related
function will also be closed.
Mark Trace: Select the trace marked by the current cursor as Trace 1, Trace 2, Trace 3, Trace 4.
Mark Frequency: Mark the frequency point on the trace. User can change the frequency value by using
the numeric key, rotary knob, direction key or touch panel menu.
Relative To: For measuring the difference between two cursors and the two cursor can be marked on
the different trace at the same time.
Properties: Scale selection, manual/automatic switch and mark line switch of X-axis.
1. X-Axis Scale: optional frequency, period, time, inverse time. The marker point reading changes the
reading unit according to the X-axis scale.
Frequency: When this type of reading is selected, “Normal” and “Fixed “cursor shows the absolute
frequency.
“Difference” cursor shows the frequency difference of difference cursor with respect to the reference
cursor. In non-zero span mode, the default reading method is “Frequency”.
Period: When this type of reading is selected, “Normal” and “Fixed “cursor shows the reciprocal of the
cursor frequency.
“Difference” cursor shows the reciprocal of the frequency difference. When the frequency difference is
zero, then the reciprocal will be infinite and the reading show as “---”.
Time: When this type of reading is selected, “Normal” and “Fixed “cursor shows the time difference
between the cursor and sweep start.
“Difference” cursor shows the sweep time difference between the difference cursor and reference
