as RMS THD with a Distortion Analyzer unless noted above.
Waveform Edit ( 4.6.2.1 ) allows modification of existing waveforms, and Waveform Synthesis (Harmonic
Analysis and Synthesis option, ( 4.6.2.3 )) creates waveforms by defining harmonic content.
Waveforms are created using this formula:
WAVEFORM =
Σ α
n
sin( nw +
δ
)
n = harmonic number
α
n
= harmonic amplitude (% of fundamental)
δ
= harmonic phase angle
For example, the above formula may use values from the following tables:
