6.10.5 Changing the marker evaluation settings
(Marker Settings)
Marker • Marker Settings
The peak marker evaluation functions can be set using the Marker Settings
softkey.
Setting a threshold (Peak Threshold)
Peak Threshold allows you to set a threshold within the range RL+20 dB to
RL-120 dB. This ensures that only values above the noise floor are
recorded for the evaluation. Values below the threshold are ignored. You
can evaluate up to 50 peaks.
To select a threshold value:
1. Press the Peak Thrsh. softkey until On appears.
The function is activated.
2. Press the Set Threshold softkey.
A table showing the threshold value appears; this value is also shown
at the same time as a horizontal line on the measurement screen.
3. Select a value with the rotary control knob, and press OK to make the
setting.
Setting a minimum signal peak excursion
(Peak Excursion)
Whereas Peak Threshold sets a threshold that the peak values for an
evaluation must exceed, Peak Excursion defines how far the peak
excursion has to be for the signal to be included as a peak in the list (setting
range 0 – 20 dB)
To select a Peak Excursion value:
1. Press the Peak Excursion softkey until On appears.
The function is activated.
2. Press the Set Excursion softkey, select a value with the rotary control
knob, and press OK to make the setting.
