Measuring Individual Harmonics - AEMC 725 User Manual

Measuring Individual Harmonics

While in %THD or %DF, individual harmonic values may be accessed.
Each harmonic is expressed in terms of it RMS magnitude and as a per-
centage of the fundamental signal for %THD, and as a percentage of the
RMS value for %DF.
push buttons select harmonics from Hdc, H01-H25.
accesses individual harmonics in an increasing order (H01, H02, H03...).
accesses individual harmonics in a decreasing order (H15, H13, H11...).
push buttons may be held down, which permits the individual har-
monics to be sequenced continuously (25 orders in 5 seconds).
