Applications (cont’d)
•
The Table "Ref.: Harmonic X" indicates, for the harmonic selected:
-
its value as a % of the fundamental
-
its phase in ° with respect to the fundamental
-
its frequency in Hz
-
its RMS voltage in V
Example of harmonic breakdown
• On CH1, inject a rectangular signal with frequency 100 Hz and
amplitude 5 V.
• On CH4, inject a triangular signal with frequency 100 Hz and
amplitude 5 V.
• Use the key
opposite
to perform automatic optimum adjustment of
the channels, the ranges, the time base and the trigger.
