●
Type
Shows the marker type. The marker type is either a normal marker (N) or delta
marker (D).
●
Ref
Shows the reference marker. Applicable only for delta markers.
●
Trace
Trace number the marker is positioned on. You can turn on a maximum of six
traces at the same time. Each trace has a different color.
●
Frequency
Frequency of a peak that was detected during the peak search. For normal mark-
ers this is a absolute value, for delta markers this is a relative value. The corre-
sponding reference marker for delta markers is indicated in the "Ref" column.
●
Level
Signal level at the marker position according to the trace detector. For normal
markers this is an absolute value, for delta markers this is a relative value. The cor-
responding reference marker for delta markers is indicated in the "Ref" column.
The unit for absolute markers depends on the selected unit. The unit for relative
markers is dB.
●
Detector
Detector that has been assigned to the EMI measurement marker.
● Δ
Limit
Shows the distance of the marker level to all active limit lines.
The order of results depends on the order in that you have loaded the limit lines
and is the same as the order in the status register.
The result is either a relative value in dB or three dashes (- - -). In case of three
dashes the marker is either
–
on a different trace than the limit line or
–
on a horizontal position that is not covered by the limit line.
The delta limit is shown only if you have assigned a detector to the measurement
marker.
●
Result
Shows the signal level at the marker position according to the detector assigned to
the corresponding marker. The result is only displayed after the final measurement
is done. The overall measurement time depends on the dwell time.
If a limit line is active, the result can have three colors.
–
green indicates that the marker has passed the limit check.
–
yellow indicates that the marker is in the margins of the limit line.
–
red and a star (*) indicate that the marker has failed the limit check.
For more information on limit lines see the documentation of the base unit.
The result is shown only if you have assigned a detector to the measurement marker.
