The Spectrogram Marker

The Spectrogram Marker allows you to analyze the recorded spectra by

means of time or frequency based navigation in the spectrogram.



You can find detailed information on how to use the Marker functions

under

The Marker function

on page 106.

The Spectrogram Marker has some additional functions:

•

Navigation:

Moves the marker along the frequency or time axis.

•

Delta Marker:

Displays the differences between markers at the same

time, at the same frequency, or freely settable markers.
