2. Control area
•
When the pointer is placed on one of a channel's parameters, it
directly opens the associated "Sensitivity/Coupling" and "Vertical
Scale"
menus.
•
The pointer validates the channels.
•
The " " symbol indicates whether the channel is selected.
3. Status area
The status area indicates the automatic measurements performed on the
signals and the selected harmonic.
The "SIGNAL" area This indicates:
- the active channel(s): ch1 to ch4 , (- - -) when the channel is not
active
-
the RMS voltage of the signal in V
-
the harmonic distortion rate (THD) in %

or "Harmonic X" area
This indicates, for the fundamental or the selected harmonic, ( Example:
Ref. Harmonic 3 ):
- its value as a % of the harmonic of the strongest amplitude
- its phase in ° in relation to the fundamental
- its frequency in Hz
- its RMS voltage in V
4. Menu bar
The same menu toolbar is used as in "Oscilloscope" mode; some menus
are adapted to the "Harmonic Analysis" mode and the others are not active.
