RF Freq
Configures the center frequency. The configured value is displayed as "RF Freq" in the
measurement settings area.
Remote command:
IFSPECT_FREQRF
on page 356
Span
Configures the frequency span, which must be at least 100 kHz. The span is distrib-
uted evenly to the left and right of the "RF Freq" on page 146. The configured value is
displayed as "Span" in the measurement settings area.
Remote command:
IFSPECT_FREQ_SPAN

5.2.2 Configuring the Bandwidth
Access : [BW]
Access VNC : [e] > "F1"
RBW ............................................................................................................................146
RBW
Defines the resolution bandwidth (RBW) of the spectrum. The resolution bandwidth
defines the minimum frequency separation at which the individual components of a
spectrum can be distinguished. Small values result in high precision, as the distance
between two distinguishable frequencies is small. Higher values decrease the preci-
sion, but increase measurement speed.
The RBW can be determined automatically by the R&S EVSG1000, or manually.
AUTO mode The RBW is determined automatically according to the sweep time
and frequency range.
Manual mode Select a predefined fixed value manually.
Remote command:
IFSPECT_RES_BW

IFSPECT_RESBW_AUTO
