Note that the measurement time for IF analysis is calculated automatically based on
the measurement time of the bargraph.

Final measurement:
Measurement Bandwidth
Defines the measurement bandwidth (or resolution bandwidth) used for the measure-
ment.
You can define a different bandwidth for the bargraph and each scan range defined in
the scan table. The R&S
ESW displays an exclamation mark if the selected measure-
ment bandwidth is not compatible to the bandwidth required by CISPR for the corre-
sponding frequency range.
If you perform a scan that is not based on a scan table, the bandwidth for the scan is
the same as for the bargraph.
The final measurement uses the bandwidths defined in the scan table, or, if the scan is
not based on a scan table (
parameters), the bandwidth of the bargraph.
The R&S
ESW supports a selected set of resolution bandwidths. If you enter a number
that is not supported, the R&S
ESW rounds the value up to next available bandwidth.
Remote command:
Bargraph:
[SENSe:]BANDwidth[:RESolution][:VALue]
[SENSe:]SCAN<sr>:BANDwidth:RESolution
[SENSe:]BANDwidth[:RESolution][:VALue]
Filter Type
Selects the type of resolution filter used in the measurement.
The available resolution bandwidths depend on the filter selection.
You can select from the following filter types.
●
Normal (3 dB)
Gaussian filter with a 3 dB bandwidth.
●
Gauss (6 dB)
Gaussian filter with a 6
bandwidth. 6
dB bandwidths that comply with CISPR and
MIL standards are available.
●
CISPR (6 dB)
Gaussian filter with a 6
bandwidth. 6
dB bandwidths that comply with CISPR stand-
ards are available.
●
MIL (6 dB)
Gaussian filter with a 6
bandwidth. 6
dB bandwidths that comply with military
standards are available.
6
dB bandwidths correspond approximately to the pulse bandwidth.
3
dB bandwidths correspond approximately to the noise bandwidth.
