Couple to Scan Trace
Couples or decouples the bargraph detector and scan detectors.
Turning on the feature has the following effects.
●
Turns on a scan detector for every active bargraph.
If you add a new bargraph detector, the corresponding scan trace is automatically
turned on.
●
Matches the scan trace number to the number of the bargraph.
If you couple bargraph and scan trace, the R&S ESW replaces the detectors of all
other active scan traces with the new detector type.

Bargraph Max Hold
Turns the display of the highest level that has been measured on any frequency since
the last "Max Hold Reset" on and off, regardless of the receiver settings.
When you turn on the max hold information, the R&S ESW shows the highest level that
has been measured for each active bargraph (detector), including the frequency where
it was measured.
Note: The little vertical line displayed in the bargraph does not represent the max hold
value. Instead it shows the highest level that has been measured for the current
receiver frequency.
You can reset the max hold bargraph with the "Reset Max Hold" button. After you have
reset the max hold bargraph, it starts collecting maximum values again.

Measurement Time
Defines the measurement time used to analyze the signal.
You can define a different measurement time for the bargraph, each scan range
defined in the scan table and the final measurement. If you perform a scan that is not
based on a scan table (
Current parameters), the measurement time for the scan is the
same as for the bargraph.
In addition, you can define a separate measurement time for fixed frequency scans.
Tip: Make sure to select a measurement time that is appropriate for the analyzed sig-
nal and that allows the various filters and detectors in the signal path to settle.
