Hi, anyone used ADS's VTB_Basics_wrk to measure PA EVM? I used its QAM64_test to test EVM.
Question 1: my simulation results show that it outputs same power when input power is different without obvious changes in setting, such as pout=10dBm@pin=-10dBm, pout=10dBm@pin=-8dBm. And there are also other input power point goes like that.

Question 2: A error that failed getting port datatype always appeared whenere I changed the Bandwidth to BW_20MHz in Tx_1Ant_Analysis instance. I just used it to measure EVM. Is there any tips in using VTB to measure EVM.
