Note
When the modulation depth is greater than 100%, the
output cannot exceed ±5VPeak (10k
Ω load).
If an external modulation source is selected, modulation
depth is limited to ± 5V from the MOD INPUT terminal on
the rear panel. For example, if the modulation depth is
set to 100%, then the maximum amplitude is +5V, and
the minimum amplitude is -5V.
