I'm having problems getting my simulation to run correctly when using the twta token . the sim works fine when i use the gain token.
the qpsk constellation looks strange when the twta token is used in place of the gain token.
attached are two files one that "works" (using the gain token) and another that doesn't work (using the twta token)
any ideas what i'm doing wrong?
thanks

Your TWTA token is NOT a TWTA model. it is a linear token. a twta model
the gain and phase are functions of the input power.
The TWTA token exits in SystemView take a look. Example TWTA-1 in the RF lib examples.
not sure where you got the G, phi model. Look at the gain, very strange.
