"video bandwidth = resolution bandwidth/10"
At this coupling ratio, noise and pulsed signals are suppressed in the video domain.
For noise signals, the average value is displayed.
This setting takes effect if you define the video bandwidth automatically (Video BW
Auto).
Remote command:
BAND:VID:RAT 0.1, see [SENSe:]BANDwidth|BWIDth:VIDeo:RATio
on page 832
RBW/VBW Manual ← Coupling Ratio
Activates the manual input of the coupling ratio.
The resolution bandwidth/video bandwidth ratio can be set in the range 0.001 to 1000.
This setting takes effect if you define the video bandwidth automatically (Video BW
Auto).
Remote command:
BAND:VID:RAT 10, see [SENSe:]BANDwidth|BWIDth:VIDeo:RATio
on page 832
Span/RBW Auto [100] ← Coupling Ratio
Sets the following coupling ratio:
"resolution bandwidth = span/100"
This coupling ratio is the default setting of the R&S ESR.
This setting takes effect if you define the resolution bandwidth automatically (Res BW
Auto).
Remote command:
BAND:VID:RAT 0.001, see [SENSe:]BANDwidth|BWIDth:VIDeo:RATio
on page 832
Span/RBW Manual ← Coupling Ratio
Activates the manual input of the coupling ratio.
This setting takes effect if you define the resolution bandwidth automatically (Res BW
Auto).
The span/resolution bandwidth ratio can be set in the range 1 to 10000.
Remote command:
BAND:RAT 0.1, see [SENSe:]BANDwidth|BWIDth[:RESolution]:RATio
on page 831
Default Coupling ← Coupling Ratio
Sets all coupled functions to the default state ("AUTO").
In addition, the ratio "RBW/VBW" is set to "SINE [1/1]" and the ratio "SPAN/RBW" to
100.
