Note:
The trace detector configured in the trace settings is used for the initial peak
search only, see
Chapter 6.10.1.2, "Trace Settings"
"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.
"CISPR Aver-
age"
Determines a weighted average signal level according to CISPR
16-1-1.
The average value according to CISPR 16-1-1 is the maximum value
detected while calculating the linear average value during the speci-
fied dwell time.
The "CISPR Average" detector is only available for the CISPR filter.
"RMS Aver-
age"
A combination of the RMS detector (for pulse repetition frequencies
above a corner frequency) and the Average detector (for pulse repeti-
tion frequencies below the corner frequency).
Lowpass filters of the second order determine the average value
(simulation of a mechanical pointer instrument).
The "RMS Average" detector is only available for the CISPR filter.

Frequency Axis Scaling
Switches between linear and logarithmic scaling for the frequency axis.
Logarithmic scaling is only available if R&S
FPL1-K54 is installed and only for f
stop
≥
1.4* f
start
.
Logarithmic scaling is not available together with CISPR trace detectors. If you select
logarithmic scaling while a CISPR trace detector is active, the trace detector is auto-
matically switched to auto detector (see also
on page 254). The sweep mode is automatically switched to FFT
mode.
By default, the frequency axis has linear scaling. Logarithmic scaling of the frequency
axis, however, is common for measurements over large frequency ranges as it enhan-
ces the resolution of the lower frequencies. On the other hand, high frequencies get
more crowded and become harder to distinguish.
