Hi, I have been researching the AMP_F block in VSS (Frequency Dependent Behavioral Amplifier) and I'm interested in trying the Large Signal Polynomial method. According to the documentation (https://awrcorp.com/download/faq/english/docs/VSS_System_Blocks/AMP_F.htm) it can model "broadband, frequency dependent" effects. However, for the 'data' field, there is this disclaimer:
Note that you cannot include both input power/voltage-dependent tables and frequency-dependent tables in the same data file.
If that's the case, then how is the frequency dependency captured, assuming you want to supply something like the following:
PIn(,dBm) POut(,dBm) PhsOut(Phs,deg) IM_2_1(,dBm) IM_1_2(,dBm) H2A(,dBm) H2B(,dBm)
-50 -40 180 -150 -152 -102 -103
-40 -30 179 -120 -124 -82 -83
-30 -21 170 -89 -96 -62 -63Any help or insight would be appreciated!
That sentence seems incorrect; perhaps outdated. Select File > Open Example..., and open the AMP_F.emp example project. See the AMP_AM_to_AM_PM_Frequency_Dependent data file, and the graph "AM to AM Response".
The wording is very specific. You can not have both types of tables (e.g. where the first column is FREQ in one, and PIn in the other) in the same data file. You CAN have a different power-dependent table per frequency.
