Function key Assigned functions
Basic measurement settings
FREQ Sets the center frequency and the start and stop frequencies for the fre-
quency range under consideration. This key is also used to set the fre-
quency offset and the signal track function.
SPAN Sets the frequency span to be analyzed.
AMPT Sets the reference level, the displayed dynamic range, the RF attenua-
tion and the unit for the level display.
Sets the level offset and the input impedance.
Activates the preamplifier (option RF Preamplifier, R&S FSW-B24).
AUTO SET Enables automatic settings for level, frequency or sweep type mode.
BW Sets the resolution bandwidth and the video bandwidth.
SWEEP Sets the sweep time and the number of measurement points.
Selects continuous measurement or single measurement.
TRACE Configures the measured data acquisition and the analysis of the mea-
surement data.
TRIG Sets the trigger mode, the trigger threshold, the trigger delay, and the
gate configuration in the case of gated sweep.
Marker functions
MKR Sets and positions the absolute and relative measurement markers
(markers and delta markers).
PEAK SEARCH Performs a peak search for active marker. If no marker is active, normal
marker 1 is activated and the peak search is performed for it.
MKR FUNC Provides additional analysis functions of the measurement markers:
Frequency counter (Sig Count)
Fixed reference point for relative measurement markers (Ref Fixed)
Noise marker (Noise Meas)
Phase noise (Phase Noise)
n dB down function
AM/FM audio demodulation
Peak list
MKR-> Used for search functions of the measurement markers (maximum/mini-
mum of the trace).
Assigns the marker frequency to the center frequency, and the marker
level to the reference level.
Restricts the search area (Search Limits) and characterizes the maxi-
mum points and minimum points (Peak Excursion).
