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.
