004_FM_Source : Jitter simulation Source

Minimum Versions: SmartSpice 4.6.5.R

The input deck shows you how to produce a single element that behaves as a Frequency Modulated (FM) source. If the modulation is small you can simulate the the input waveform with a variation like Jitter to see the effect through subsequent circuits.

The Waveform results show how the final frequency modulated waveform output looks in the time domain and after a jitter analysis in SmartView to simulate the sort of drift in frequency you may see from an non-ideal source. (This is not a true random jitter variation, but allows simulation of circuitry fed by a variation you may see from a real source).

Note: You can change the modulating source to give different jitter coverage levels as required.
