Initial peak search results - Marker Table
As a result of the initial peak search, the active markers are set to the positive peaks of
the measured signal.
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.
The active marker levels and positions are displayed in the Marker Table.
(Note: the marker results are also displayed in the Result Summary; in addition, the
Marker Table contains the marker results for those markers for which no final EMI test
is performed.)
Final test results - Result Summary
The results of the final EMI tests at the active marker frequencies are displayed in the
Result Summary.
The Result Summary provides the following information:
Label Description
Type Marker name
Ref Reference marker for delta markers
Trace Assigned trace
X-value Marker x-value (frequency for final test)
Y-value Marker y-value (level during inital measurement)
Final Test Detector used for final EMI test
Line name Line activated for limit check
Δ Limit Delta between measured level and limit line (if active)
The value is colored to indicate the following states:
●
green: does not exceed limit
●
yellow: within margin
●
red: exceeds limit
Final Result Value measured during final EMI test using specified detector at marker frequency
