Abstract: Systems and methods for dynamic multitone simulation scenario planning. A method commences upon accessing a server in a circuit simulation environment to generate a multitone simulation signal to accurately simulate non-linear circuit characteristics. The tones of the multitone simulation signal are derived from a subset of possible tones based on certain properties. Some properties serve to eliminate harmonic and intermodulation products that conflict with the tones in the subset. The amplitude and phase for each tone is determined based on certain constraints. A multitone transient signal is generated from the selected tone subset and associated tone attributes to facilitate a circuit simulation. Characteristics of the multitone transient signal and/or simulation results from the circuit simulation can be analyzed to facilitate dynamically planning simulation scenarios that use multitone simulation signals.

Abstract: The present invention is directed to communication systems and techniques thereof. More specifically, embodiments of the present invention provide a calibration system for optical transmitter. The calibration system provides a predetermined set of operating parameters to the optical transmitter and measures the second harmonic value of the transmitter output. A calibrated set of parameters is determined by selecting operating parameters associated with the minimum second harmonic value. There are other embodiments as well.
