Dwell Time
Sets the dwell time for the EMI marker measurement.
For more information see "Measuring at the Marker Position" on page 276.

Marker Table
If more than two markers have been activated, the application adds a marker table to
the display below the diagram area. The size of the table depends on the number of
markers that are active. It contains the following information for every marker.
●
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.
