Modulating Source
The waveform generator will accept an internal or external modulation
source for PM.
• Modulating source: Internal (default) , Other Channel , or External.
• If you select the External source, the carrier waveform is modulated
with an external waveform. The phase deviation is controlled by the
±5 V signal level present on the rear-panel
Modulation In connector.
For example, if you have set the deviation to 180 degrees, then a +5 V
signal level corresponds to a 180 degree phase shift. Lower external
signal levels produce less deviation.
• Front-Panel Operation : After enabling PM, press the
Source
softkey.
• Remote Interface Operation :
