Coupled
(Harmonic command) Makes the frequency of one output a multiple of another output
for the ac voltage or ac power functions (sine waves only). For example, in dual ac
voltage, have the frequency of the voltage output on the Calibrator front panel
NORMAL terminals at 60 Hz and the frequency of the voltage output on the AUX
terminals at the 7th harmonic (420 Hz). The range for the harmonics is 1 to 50.
Parameters: <value>, PRI
<value>, SEC
Example:
(fundamental at 5520A NORMAL terminals)
(fundamental at 5520A AUX terminals)
HARMONIC 5, PRI
Load the fundamental frequency at the primary (PRI) output (NORMAL terminals), and
the 5th harmonic frequency is at the secondary output (AUX terminals). For example, if
the fundamental frequency output is 60 Hz, the harmonic frequency output is 300 Hz.
