influence on loop gain from OscPort2?

Question asked by shoujun.yang on Aug 31, 2006
When I do small signal loop gain analysis, the loop gain is dependant of the Z of OscPort2. Up to now, I don't know which is the reasonal value of loop gain. How to judge it? The documentation doesn't tell it according to my knowledge.

How much does the external analyzing Port (both OscPort and OscPort2) have influence on the small signal or large signal loop gain?

Can I use the gotten loop gain to calculate loaded-quality factor? If so, how can I get this value?
