RE : calculating the output power of a Quartz oscillator

david j james

Help !

I am designing a Crystal Oscillator ( which is a complex load) and trying to calculate Output power (to avoid over loading the crystal). I am using pss to simulate it and I get a tran waveform.

The power is complex so it is not easy to calculate. For example in a transient simulation phase information isn't readily available.

When I create calculations in calculator tool  get several different answers, and I am not sure which to trust

How should I calculate the output power?

What is the 'recommended' method?
