Claim 4:
5. The distributed RAN of claim 1, wherein each of the one or more selected receive circuits comprises:
a bandpass filter configured to pass the at least one RF test signal in the selected receive band and reject the at least one RF test signal outside the selected receive band;
a low-noise amplifier (LNA) configured to amplify the at least one RF test signal to a receive power;
a frequency converter configured to convert the at least one RF test signal from the selected receive band to a selected intermediate frequency (IF) band;
a second bandpass filter configured to pass the at least one RF test signal in the selected IF band and reject the at least one RF test signal outside the selected IF band;
a variable gain amplifier (VGA) corresponding to a minimum effective gain value and a maximum effective gain value, the VGA configured to convert the at least one RF test signal from the receive power to an effective power; and
the analog-to-digital converter (ADC) configured to convert the at least one RF test signal into the digital test signal.
