"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 6.5.1.6, "Which Data May Pass: Filter Types",
on page 406.
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 5.13.3.1, "Resolution Bandwidth and Filter Types", on page 290.
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 6.5.1.3, "Coupling VBW and RBW", on page 404.

Sweep/Average Count
Defines the number of sweeps to be performed in the single sweep mode. Values from
0 to 200000 are allowed. If the values 0 or 1 are set, one sweep is performed.
The sweep count is applied to all the traces in all diagrams.
If the trace modes "Average", "Max Hold" or "Min Hold" are set, this value also deter-
mines the number of averaging or maximum search procedures.
In continuous sweep mode, if sweep count = 0 (default), averaging is performed over
10 sweeps. For sweep count =1, no averaging, maxhold or minhold operations are per-
formed.
For more information see chapter 6.5.1.8, "How Much Data is Measured: Sweep Points
and Sweep Count", on page 407.
