Max Drift Shows the highest difference to the initial (nominal) frequency that was measured
in the half decade.
Level Drift Shows the difference to the initial (nominal) level that was measured in the half
decade.
If you perform more than one measurement (averages) in the half decade, the
value is updated for each single measurement. The last value that has been mea-
sured in the half decade will remain in the table.

Spectrum Monitor
The spectrum monitor shows the spectrum for the half decade that is currently mea-
sured.
Span
The span on the x-axis is defined by the start and stop frequency of the half decade
that is currently measured.
Y-axis scale
The scale of the y-axis is automatically determined according to the signal characteris-
tics.
In I/Q mode, the result display contains two traces.
●
The yellow trace ("raw trace") represents the live signal with the actual center fre-
quency currently measured.
