Harmonic Analysis Mode - Display
Harmonic Analysis Mode (cont'd)
Composition In this mode, the display is divided into 4 functional areas:
1. Display area
Displays the result of harmonic analysis of the selected traces.
The harmonic analysis of the ch1 and ch3 trace is shown in a darker color,
while the trace of ch2 and ch4 are displayed in a lighter color (or the same
color as the trace).
The display appears as a bar chart, with its vertical axis graduated in terms of
the percentage of the fundamental amplitude (from 0% to 100% every 25%).
The horizontal axis represents the harmonics, i.e.:
•
the fundamental (F) and the first 15 consecutive harmonics
•
the fundamental (F) and the even harmonics from 2 to 30
•
the fundamental (F) and the odd harmonics from 3 to 31
Use this button to display another series of harmonics:
Consecutive harmonic ranges
- from 2 to 16,
- from 17 to 31,
- from 32 to 46,
- from 46 to 61
Even harmonic ranges
- from 2 to 30,
- from 32 to 60
Odd harmonic ranges
- from 3 to 31,
-
from 33 to 61
With this breakdown of the harmonics, the stylus can be used to select the
fundamental (F) or one of the harmonics ( Example: Ref. Harmonic 5 ) to
perform automatic measurements on the selected element.
•
The " " symbol indicates the harmonic selected.
•
See §. "Display" Menu for selection of the harmonics.
