Modulating Source
The function generator will accept an internal or external modulation source for
AM.
– Modulating source: Internal or External. The default is Internal.
– If you select the External source, the carrier waveform is modulated with an
external waveform. The modulation depth is controlled by the ±5V signal level
present on the rear-panel Modulation In connector. For example, if you have
set the modulation depth to 100%
, then when the modulating signal is at +5
volts, the output will be at the
maximum
amplitude. When the modulating signal
is at -5 volts, then the output will be at the
minimum
amplitude.
– Front-Panel Operation: After enabling AM, press the Source softkey.
– Remote Interface Operation:
