Follow the steps below to calibrate the USRP:

• check Conducted Connection
• Set USRP Cal Facrotor, Attenuator, Cable Length to 0
• Spoofing Mode to Asynchronous

• Connect RF out of USRP to spectrum analyzer or RF power meter. In case of spectrum analyzer set up CF to 1575.42 MHz and bandwith to 10 MHz and switch on power measurement.
• Set DUT input power to -20 dBm
• Push Scenario Start

• Measure RMS Power of the generated signal
• Calculate:

USRP Cal Factor, dB = Dut Input Power, dBm - Power in Band, dBm
