Options can be set using the right mouse button or the context menu (see “ FFT/Sonagram Context Menu ”
on page 71). It is possible to remove the tuning FFT or Sonagram in the View Menu.
Making measurements
With the four cursors it is possible to make measurements in the frequency and time domain. To enable
the time cursors, click into the sonagram to freeze the screen. Then click with the right mouse button to
get the menu to set the time cursors.
 T1 Add first cursor to the actual mouse position
 T2 Add second cursor to the actual mouse position
 Move Move T1 cursor and T2 cursor simultaneously
It is also possible to drag the cursor to a new location. If the cursor line gets in the upper our lower part of
the window, then the window will scroll automatically.
Sonagram (HF, SUB, DIR and SAT)
FFT Type Start Frequency End Freqeuncy
Sonagram HF Offset Frequency Bandwidth
Sonagram SUB Offset Frequency Bandwidth
Sonagram DIR Offset Frequency – Bandwidth/2 Offset Frequency + Bandwidth/2
Sonagram SAT Offset Frequency – Bandwidth/2 Offset Frequency + Bandwidth/2
Oscilloscope
In general, an oscilloscope is used to measure voltage over time. However, the oscilloscope displays a rel-
ative and un-calibrated value. After obtaining the measurement time, frequency can be determined.
By clicking on the graph, the display will be paused and measurement cursors appear for both axis.
Several Color schemes are available through the right-click menu.
