Sir i have a few questions in RF measuring equipments. When i am setting a particular frequency, and setting signal strength to say -80dbm. what exactly are we doing? Are we setting the equipment to BER -80 by feeding noise? If this is noise we feed to control the signal strength, what is the modulated wave, carrier wave we feed. Sorry fundamental questions. an you beiefly explain me
