Figure 4: Scan Sequence adjustment with "Scan-Search-Measure"
Note 1: Please be carefully with dynamic range settings. Please set attenuator to the maximum value and
turn off pre-amp in case you don’t know the signal level to avoid to destroy the spectrum analyzer. If you
are unsure about the interference level, please use additionally an external attenuator for the first test.
This one can be removed for further tests when you are sure that the maximum interference level of your
DUT are not higher than the reference level of your spectrum analyzer.
Note 2: Please be carefully with measurement with a LISN and use always a transient limiter for such tests
to protect the spectrum analyzer.
Note 3: The dynamic range settings in [Scan Table] is only for the trace and not for the measurement meter.
They need to be adjusted via [Ampt] button (see description “Dynamic Range for Measurement Meter”)
For the trace detector selection, please select [Trace]  [Trace Det] (e.g. Average). Here you can also
activate a second or more traces with different detectors or adjustments
Scan Sequence Settings:
For the next adjustment please select again [Meas Setup] and select [Scan Sequence]
 In this menu, you can decide the sequence of your test.
 In case you want to record only the trace without any further measurements, you should select
[Scan Only]
 In case you measured already a trace and you want to search for the peaks, please select [Search
Only]
