Ankit,
First, calibration is outside the scope (so to speak) of GNU Radio and
USRPs, so absolute measurements are going to require test equipment.
But, you can determine SNR and the peak amplitude above the noise floor
for some simple signals by viewing them on uhd_fft or a similar program.
Peak hold and averaging functions may get you close to what you want.
Fortunately, after a while, you won't be new to GNU Radio any more.
