Note that the ratio defined with this remote command (RBW/span) is reciprocal to that
of the coupling ratio (span/RBW).
Parameters:
<Ratio> Range: 0.0001 to 1
*RST: 0.01
Example: BAND:RAT 0.1
Manual operation: See "Span/RBW" on page 473
[SENSe:]BWIDth[:RESolution]:TYPE <FilterType>
[SENSe:]BANDwidth[:RESolution]:TYPE <FilterType>
This command selects the resolution filter type.
When you change the filter type, the command selects the next larger filter bandwidth if
the same bandwidth is unavailable for that filter.
The EMI-specific filter types are available if the EMI (R&S FSV3-K54) measurement
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 326.
Parameters:
<FilterType> CFILter
Channel filters
NORMal
Gaussian filters
P5
5-pole filters
The 5-pole filter is not available for FFT sweeps.
RRC
RRC filters
CISPr | PULSe
CISPR (6 dB) - requires EMI (R&S FSV3-K54) option
Return value for query is always
PULS
.
MIL
MIL Std (6 dB) - requires EMI (R&S FSV3-K54) option
*RST: NORMal
Example: BAND:TYPE NORM
Example: See Chapter 12.15.1, "Programming example: performing a
basic frequency sweep" , on page 1415.
