Peak Excursion and Peak Threshold example—the settings for the trace in the following
image are:
——Threshold: –10 dB
——Excursion: 1 dB
——Scale = 1 dB / Division.
Peak A = Valid Peak (Above Threshold and Excursion Settings)
Peak B = Invalid Peak (Below 1 dB Excursion Setting)
Peak C = Invalid Peak (Below –10 dB Threshold Setting)
Marker Functions
Marker functions are used to change FieldFox frequency or distance settings to those of the active
marker.
How to use Marker Functions
1. Activate the marker to move.
2. Then press Mkr ->/Tools
3. Then Mkr -> (this step not required for all modes)
4. Then choose one of the following:
— Mkr -> Center
span) The center frequency of the measurement becomes the value of the active marker.
The frequency span is adjusted accordingly.
— Mkr -> Delay

— Mkr-> RefLev
becomes the magnitude of the active marker.
— Mkr->TuneFreq
becomes the frequency of the active marker (When AM Metrics or FM Metrics are
selected this softkey is inactive).
