USRP2 - Front end calibration data

Description

Characteristics of USRP's front end were measured against an RF reference:

1. Agilent ESG Vector Signal Generator (E4438C) for the USRP2's receiver
   USRP2 receiver measures the frequency and power level of known signals sent from signal generator.
2. Agilent ESA-E Series Spectrum Analyzer (E4405) for USRP's transmitter
   USRP2 transmitter sends specified signal with frequency and amplitude level that is measured by spectrum analyzer.

1. sgfrequency_in - signal generator frequency (Hz)
2. sgpower_in - signal generator power (dBm)
3. gain_in - usrp receive path gain (dBm)
4. rxfrequency_meas - usrp measured frequency (Hz)
5. rxpeakpower_meas - usrp measure power (dBm)
