Ford,
The intercept points are fictitious. They are calculated by taking a
measurement in the linear region of the device under test. The measurement for
third-order intercept (TOI) is made with two tones at a reasonable level. The
resulting inter-mod products are measured on a spectrum analyzer and the
intercept point is calculated.
There are many discussions of TOI on the web. Just google "third order
intercept" or "second order intercept".
