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
— Activate the marker to move.
— Then press Mkr ->/Tools
— Then Mkr -> (this step not required for I/Q Analyzer mode)
Then choose one of the following:
— Mkr -> Center
(Not available in DTF, I/Q Analyzer (waveform), or SA mode with zero span) The
center frequency of the measurement becomes the value of the active marker. The frequency
span is adjusted accordingly.
— Mkr -> Delay
(NA mode ONLY.) The group delay value of the active marker becomes the
electrical delay setting of the trace. Learn how to set group delay format in “Calibration
Settings” on page 93e. Learn more about electrical delay in “Electrical Delay” on page 97.
— Mkr-> RefLev
(IQ Analyzer (NOT waveform) and SA mode ONLY) The acquisition becomes the
magnitude of the active marker.
— Mkr->TuneFreq
(SA mode with Tune & Listen ONLY) The Tune & Listen Frequency becomes the
frequency of the active marker.
The following applies to DTF Measurements ONLY:
