For more information see Chapter 8.5.1.3, "Coupling VBW and RBW", on page 461.
"Sine[1/1]"
"Video Bandwidth" = "Resolution Bandwidth"
This is the default setting for the coupling ratio RBW/VBW and is rec-
ommended if sinusoidal signals are to be measured.
"Pulse[0.1]"
"Video Bandwidth" = 10 x "Resolution Bandwidth"
or
"Video Bandwidth" = "10 MHz" (= max. VBW)
Recommended for pulse signals
"Noise[10]"
"Video Bandwidth" = "Resolution Bandwidth/10"
Recommended for noise measurements
"Manual"
The coupling ratio is defined manually.
The RBW/VBW ratio can be set in the range of 0.001 to 1000.

Filter Type
Defines the filter type.
The following filter types are available:
●
Normal (3dB)
●
Channel
●
RRC
●
5-Pole (not available for sweep type "FFT")
●
CISPR (6 dB) - requires EMI (R&S FSW-K54) option
●
MIL Std (6 dB) - requires EMI (R&S FSW-K54) option
For more information see Chapter 8.5.1.6, "Which Data May Pass: Filter Types",
on page 463.
Note: The EMI-specific filter types are available if the EMI (R&S FSW-K54) measure-
ment option is installed, even if EMI measurement is not active. For details see Chap-
ter 7.13.3.1, "Resolution Bandwidth and Filter Types", on page 334.
The RBW filter configured in the bandwidth settings is identical to the filter configured
in the EMI configuration.

Default Coupling
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.
For more information see Chapter 8.5.1.3, "Coupling VBW and RBW", on page 461.
