Resolution Bandwidth (RBW Mode/Res BW)
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:

Configuring the Amplitude (Y-Axis)
Access
: [Ampt]
Access VNC
: [w]
The amplitude settings configure the y-axis of the spectrum.

Ref Level
The reference level determines the maximum power level displayed in the spectrum.
The reference level should be set as close as possible to the highest expected power
level to avoid overload at the RF input or signal clipping.
Remote command:
Y-Range
Determines the displayed power level range on the y-axis of the spectrum. The range
starts at the specified
at the top of the diagram.
RF Mode
Defines the RF attenuation mode to be used.
"Low Noise"
15 dB pre-amplification
Provides a high sensitivity. Suitable when scanning the area for dis-
tant signals.
"Norm"
0 dB
Provides a normal sensitivity.
"Low Dist"
15 dB attenuation
Provides a low sensitivity. Suitable when analyzing a nearby signal, to
avoid overload due to high-level signals.
