This multiplier has a bandwidth of 30 MHz for the carrier (signal) and a
bandwidth of 4 MHz for the modulation signal. The waveform output from CH1
is the result of the following calculation.
CH1out = CH1 setting value
A CH2 signal of 5 V (full scale) gives 100% modulation. When the CH2 signal
is minus, the CH1 signal is inverted.
The multiplied value of CH2 is expressed as a % and is displayed at the bottom
right of the CRT screen (see next example).
Max:
100.00%
Min:
0.00%
NOTE. When multiplication results in an output that exceeds 5 Vp-p, the signal
may be distorted.
Add The CH1 waveform is added to the waveform output from
CH2. See Figure 3 -157.
