●
For gated measurements, the maximum RBW is restricted to 3 MHz. If the current
RBW is larger when you enable gating, the RBW is automatically reduced to
3
MHz. See Chapter 6.6.2, "Gating" , on page 492.
●
For EMI measurements using the quasipeak detector, the 1 MHz RBW filter is not
available (see Chapter 5.13.3.1, "Resolution bandwidth and filter types" ,
on page 326).

Automatic Peak Search
If activated, a peak search is performed automatically for all active markers after each
sweep.
If Auto peak search and limit lines are active, the active markers are set to the peak
delta values between the measured signal and the limit lines.
Note: The general search functions Auto Max Peak Search / Auto Min Peak Search
are not available for EMI measurements.

Dwell Time
Sets the dwell time for the EMI marker measurement.
For more information see Chapter 5.13.3.2, "Detectors and dwell time" , on page 327.

Final Test Detector
Defines the detector to be used for the final EMI test at the marker frequency.
This setting is only available if the EMI (R&S FSV3-K54) measurement option is instal-
led. CISPR detectors are only available after selecting a CISPR RBW or filter (see
"Res BW CISPR" on page 342).
For details, see Chapter 5.13.3.2, "Detectors and dwell time" , on page 327.
Note: The trace detector configured in the trace settings is used for the initial peak
search only, see Chapter 7.5.1.2, "Trace settings" , on page 586.
"Off" No final test is performed.
"PositivePeak" Determines the maximum signal level that was detected during the
specified dwell time.
"Average" Determines the average signal level of the samples that were collec-
ted during the specified dwell time.
"Quasi-Peak" Determines the maximum signal level weighted to CISPR 16-1-1 that
was detected during the dwell time.
The "Quasi-Peak" detector is only available for the CISPR filter, and
not for an RBW of 1
MHz.
