MODULATION
73
Range Depth 0%~120%
Default depth 100%
Note When the modulation depth is greater than 100%, the
output cannot exceed ±5VPeak (10kΩ 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.
Selecting the (AM) Modulation Source
The function generator will accept an internal or external source for
AM modulation. The default source is internal.
