Modulating Source

Select the modulating source. Most function generators will accept an internal or external modulating source. The default is Internal.

The specific features and functionality available in this application will vary depending on the instrument and model number. Some of the parameters and functionality described here might not be available for a particular instrument. The application will show only those parameters and parameter ranges available for your specific instrument.

If you select the External source, the carrier waveform is modulated with an external waveform. The modulation depth is controlled by the signal level present on the function generator's external modulation connector. For function generators with multiple output channels, you can also select one of the other channels as the modulating source.
