No, it doesn't show dBm. It shows "dB", relative to an arbitrary chosen digital full-scale value. Best regards, Marcus On 07/11/2017 01:26 AM, Muhammad, Siraj wrote: > > Thank you very much, Marcus! > > But your fosphor RFNoC block does show data in dBm. Can you please > explain how is that don

Thank you very much, Marcus! But your fosphor RFNoC block does show data in dBm. Can you please explain how is that done? Is there a reference I can look at regarding the calibration of the USRP and converting to dBm? Thanks again for other clarifications. Best regards, Siraj ___

Dear Siraj, only regarding the dBm issue: The USRP is not calibrated. There's no dBm standard anywhere in the system, only digital power (which is really just the magnitude square of the complex samples), which is /proportional/ to the physical power, but not the same. The proportionality factor

Hello All, I have posted several questions previously trying to understand something but it only got me more confused. So let me put this straight. 1- I am trying to read the output of the Log Power RFNoC block *in dBm*. 2- I want to write a CE that compares these samples against a threshold ente
