R&S ESU
Example:
A spectrum is displayed with a large span after PRESET. A signal off the center is to
be examined in detail:
[PRESET]
[MKR->]
[CENTER=MKR FREQ] The center frequency is set to the marker frequency.
[SPAN]
NEXT PEAK The NEXT PEAK softkey sets the active marker/delta marker to the next lower peak
value on the trace.
For further information refer to the descriptions in section
PEAK" on page
NEXT PEAK The NEXT PEAK RIGHT softkey sets the active marker/delta marker to the next
RIGHT lower peak value to the right side of the current marker position on the selected
trace.
For further information refer to the descriptions in section
PEAK RIGHT" on page
NEXT PEAK The NEXT PEAK LEFT softkey sets the active marker/delta marker to the next lower
LEFT
peak value to the left side of the current marker position on the selected trace.

SEARCH
The SEARCH LIMITS softkey limits the search range for maximum or minimum
LIMITS search. The softkey switches to a submenu in which the search range limits can be
set in the x and y direction.
LEFT LIMIT RIGHT LIMIT
THRESHOLD
SEARCH LIMIT OFF
LEFT LIMIT The LEFT LIMIT and RIGHT LIMIT softkeys define the two vertical lines F1 and F2
RIGHT LIMIT in the frequency domain (span > 0) and T1 / T2 in the time domain (span = 0).
For further information refer to the descriptions in section
LIMIT RIGHT LIMIT" on page
THRESHOLD The THRESHOLD softkey defines the threshold line.

R&S ESU is set to the default setting.
MARKER 1 is switched on and automatically jumps
to the largest signal of the trace.
The span is adapted in such a way that the minimum
frequency (= 0 Hz) or the maximum frequency is not
exceeded.
The span can, for example, be reduced using the
rotary knob.
