Note

If an external modulation source is selected, the
SUM amplitude is controlled by the ± 5V from the
MOD INPUT terminal on the rear panel. For
example, if the SUM amplitude is set to 50%, then
the maximum amplitude (150% of the carrier ) will
be at +5V, and the minimum amplitude (50% of
the carrier) will be at -5V.
