SPAN Provides functionality to configure the frequency span.
In the realtime application, the span is coupled to the RBW and restricted
to 40 MHz.
AMPT (SCALE) Provides functionality to configure amplitude or level characteristics, for
example:
●
the reference level
●
the attenuation
●
the input impedance
●
the scale of the level axis
●
the preamplifier
AUTO SET Provides functionality to automatically define various parameters like the
level or frequency.
BW Provides functionality to define the resolution and video bandwidth.
In the realtime application, the RBW is coupled to the span. Video band-
width is not available.
SWEEP Provides functionality to configure the sweep, for example:
●
the measurement time
●
the number of measurement points
●
the measurement mode (single or continuous measurements)
In the realtime application, the number of measurement points is a fix
value (801 points).
TRACE Provides functionality to configure data acquisition and analyze mea-
sured data, for example:
●
the trace mode
●
the detector
TRIG Provides functionality to configure triggered and gated measurements,
for example:
MKR Provides functionality to activate and position absolute and relative mark-
ers (markers and delta markers).
PEAK SEARCH Performs a peak search for active markers.
If no marker is active, Marker 1 is activated and the peak search is per-
formed for it.
MKR FUNC Provides additional analysis functions of the measurement markers, for
example:
●
the frequency counter
●
the noise measurement
●
the phase noise measurement
●
the AM/FM audio demodulator
In the realtime application, marker functions are not available.
MKR➙ Provides functionality to position and control markers, for example:
●
to position the marker on the center frequency
●
to define the marker search area
●
to configure the peak excursion
