Modulation Mode AM (Amplitude Modulation)
This modulation mode is switched on by operating the key INT or EXT.
Modulation frequency and depth:
internal:
1 kHz fixed, modulation depth 30 % fixed
external:
0 Hz... 200 kHz, modulation depth depends on the amplitude of the modulation signal
Example: Amplitude Modulation (AM), internal
