Electric Field Measurement of the Living Human Body for Biomedical Applications: Phase Measurement of the Electric Field Intensity

Figure 2

Schematic block diagram of the experimental system. The system consisted of TX and RX subsystems and a base frequency oscillator. Both of the subsystems had a PC, a USRP (SDR peripheral), an external amplifier, an RF transformer, and an antenna. Because the two USRPs had the same reference clock, the internal oscillators were locked in phase.
