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
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 7.6.1.3, "Coupling VBW and RBW", on page 318.

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 performed.
For more information, see Chapter 7.6.1.8, "How Much Data is Measured: Sweep
Points and Sweep Count", on page 321.
For spectrogram displays, the sweep count determines how many sweeps are com-
bined in one frame in the spectrogram; that is: how many sweeps the R&S FPL1000
performs to plot one trace in the spectrogram result display. For more details, see
"Time Frames" on page 400.
Remote command:
[SENSe:]SWEep:COUNt on page 772
[SENSe:]AVERage<n>:COUNt on page 818
Sweep Points
Defines the number of measured values to be collected during one sweep.
For details see Chapter 7.6.1.8, "How Much Data is Measured: Sweep Points and
Sweep Count", on page 321.
All values from 101 to 100001 can be set. The default value is 1001 sweep points.
For EMI measurements, 200001 sweep points are available.
