I have a dso6254bd where it is possible to comnect one probe on a audio source and select DDS to generates a modulated signal AM or FM.
Now, i buy the dso4254c, but there is no options that i can found to select the source of the signal to be modulated.
How can i acomplish that on the dso4254c osciloscope?
Using AWG? But i think AWG is for light waves forms!
