With 1 V input, 100% amplitude modulation is possible. Figure E-13 shows
100% modulation.
Figure E 13: 100% Amplitude Modulation
Internal AM Mode. This mode can be used when the CH2 output Option 02 is
installed. This mode amplitude modulates the CH1 signal with the CH2 signal.
Unlike the external AM mode discussed above, in order for this circuit to also be
used as a multiplier, such operations as automatically applying an offset to the
CH2 signal are not done.
100% modulation occurs when the CH2 signal is 5 V (full scale). When this
signal is negative, the CH1 signal is inverted. The value calculated with 5 V set
as 100% is displayed at the bottom right of the SETUP menu CRT screen.
