Hi Andrew,
In "Lib:analoLib/cell: port" cdf parameters with "Display Multi sinusoid" option limited the number of frequencies as "1", if use more than 1 the "pss" analysis not recognizing rest of frequencies tones. [in IC6.1.7-64b.500.9 version]. Hope you have solution to recognize the rest of the frequency tones.
