S-Parameter Optimizer Not Recognizing S[1,1]

[M3K33L]

Hello,

I am unsure if this is a bug or if I’m doing something wrong, but I tried to match my schematic to the example schematic for optimizing S-parameters and have been getting this issue:

Error in ‘Eqn2’: Wrong index for ‘S’ in equation “min(dB(S[1,1]))”.

I am attaching an image of the issue and my schematic. Please help.

Please post the .sch file.

In S-parameter setups, the capital S generally seems to be an unlucky choice for a variable name.

Indeed. Didn’t see that 🙂
