OPERATION

Example:

DEP= 100%

Note

When the modulation depth is greater than

100%, the output cannot exceed ±5VPeak

(50Ω load).

If an external modulation source is

selected, modulation depth is limited to

±5V from the MOD input port 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.
