R&S FSQ Signal Analyzer - Rohde & Schwarz

R&S FSQ Instrument Functions
Example
Analyzer Mode
A spectrum is displayed with a large span after PRESET. A signal off the center is to
be examined in detail:
[PRESET] R&S FSQ is set to the default setting.
[MKR->] MARKER 1 is switched on and automatically jumps to
the largest signal of the trace.
[CENTER=MKR FREQ] The center frequency is set to the marker frequency.
The span is adapted in such a way that the minimum frequency
(= 0 Hz) or the maximum frequency is not
exceeded.
[REF LEVEL = MKR LVL] The reference level is set to the measured marker level.
[SPAN] The span can, for example, be reduced using the rotary
knob.
NEXT PEAK The NEXT PEAK softkey sets the active marker/delta marker to the next lower maximum
of the selected trace.

The NEXT PEAK RIGHT softkey sets the active marker/delta marker to the next
lower maximum right of the current marker position on the selected trace.

The NEXT PEAK LEFT softkey sets the active marker/delta marker to the next lower
maximum left of the current marker position the selected trace.

THRESHOLD
SEARCH LIMIT OFF
The SEARCH LIMITS softkey limits the search range for maximum or minimum
search. The softkey switches to a submenu in which the search range limits can be
set in the x and y direction.
The LEFT LIMIT and RIGHT LIMIT softkeys define the two vertical lines F1 and F2
in the frequency domain (span > 0) and T1 / T2 in the time domain (span = 0). The
search is performed between these lines in the frequency and time domain
If only LEFT LIMIT is enabled, line F1/T1 is the lower limit and the upper limit corresponds
to the stop frequency. If RIGHT LIMIT is also enabled, it determines the
upper limit.
