Hello, This may seem like a really simple question, but If I wanted to attenuate my signal coming out from a USRP source block in GRC, say by 80 dB,, how would I go ahead and do that? Would I just add a multiply constant block after my USRP source block to scale down the incoming signal's amplitude? Would I be able to check my attenuated signal through the QT frequency plot block?
Thanks, Jose
