Hi,
I tried to make this:
-Sweep a x variable 1 to 100
-performs S parameter simulation (20 freqs)
and I wish
Diff (x) =dB(S21)(x) -dB(S21)(x-1)
Is it possible in ADS ?
Because X and S21 are [100,20] arrays , I tried to write this measurement equation in my schmatic : Diff=dB(S21)-dB(S21)[indep(X,2),::] and many other manners....
but it doesn't work !
HELP ME PLEASE !!

If you write those equations directly, it will not work."Diff" function is reserved by ADS and it calculates the simple numerical first derivative.
Instead, you should use-for instance-"Differential_sparameters".
OK,
I write "Diff" to simply the post, my real variable is "my_diff_S21"...
Another idea ?
