Claim:
1. A circuit comprising: a signal source; an output signal port; a signal propagation channel between the signal source and the output signal port; electromagnetic interference generation circuitry that is physically positioned within a proximity to the signal propagation channel on the circuit that enables electromagnetic interference generated by the electromagnetic interference generation circuitry to interact with the signal propagation channel to introduce jitter into an electronic signal generated by the signal source as propagates through the signal propagation channel to the output signal port; and calibration circuitry configured to have a plurality of possible settings, each of at least some of the settings resulting in a different amount of the electromagnetic interference generated by the electromagnetic interference generation circuitry, in order to control the amount of jitter introduced into the electronic signal by the electromagnetic interference generation circuitry.
