The detector to be used for the final EMI test can be defined differently for each fre-
quency, thus the detector is configured in the EMI marker settings, see "Final Test
Detector" on page 264.

Filter Type
Defines the filter type.
The following filter types are available:
●
Normal (3dB)
●
Channel
●
CISPR (6 dB) - requires EMI (R&S FPL1-K54) option
●
MIL Std (6 dB) - requires EMI (R&S FPL1-K54) option
For more information see Chapter 7.6.1.6, "Which Data May Pass: Filter Types",
on page 320.
Note: The EMI-specific filter types are available if the EMI (R&S FPL1-K54) measure-
ment option is installed, even if EMI measurement is not active. For details see "Reso-
lution Bandwidth and Filter Types" on page 253.
The RBW filter configured in the bandwidth settings is identical to the filter configured
in the EMI configuration.
Remote command:
[SENSe:]BANDwidth[:RESolution]:TYPE on page 770
RBW
Defines the resolution bandwidth. The available resolution bandwidths are specified in
the data sheet. Numeric input is always rounded to the nearest possible bandwidth.
If "Auto" is selected, the resolution bandwidth is coupled to the selected span (for span
> 0). If the span is changed, the resolution bandwidth is automatically adjusted.
If the resolution bandwidth is defined manually, a green bullet is displayed next to the
"RBW" display in the channel bar.
For more information see Chapter 7.6.1.1, "Separating Signals by Selecting an Appro-
priate Resolution Bandwidth", on page 317.
Note: Restrictions.
●
For EMI measurements using the quasipeak detector, the 1 MHz RBW filter is not
available (see "Resolution Bandwidth and Filter Types" on page 253).
