Hi mohammad,Thank you for reply,you can measure received power in the way you suggested .But the actual power that received at BER analyzer , can be seen from
BER visulizer>Right click>comoponent results>total power(dB) or (mW)
In this way it is very easy to plot total received power and BER graph.We are also discussing this in another forum so if you have any question or suggestions ,discuss it to same topic in another forum which already countinue.
