How to get maximum value of s11 Trace

Hello

i did a sp-Analysis and now i want to extract the maximum value of the s11 trace and the corresponding frequency.

I already tried ymax() in the calculator but i am suspecting it only works on transient Signals.

    Use mag() first before taking the ymax(). The issue is that s11 will be complex - and when plotted on a rectangular graph, it will plot the magnitude automatically - however, the ymax() function doesn't know that is what you want with a complex waveform, so you need to do an explicit mag() first (or db20 or whatever you want to do on the complex waveform).
