Tag Amp and Tag Phase (RFID)
Menu Path:
Tag Amp measures the amplitude from the RF Radio Frequency: A generic term for radio-based technologies, operating between the Low Frequency range (30k Hz) and the Extra High Frequency range (300 GHz). envelope and Tag Phase measures the phase of tag to CW. Tag amplitude decreases and distorts as the phase of the tag gets close to 90 degrees as shown below.
RF Amplitude and Tag Phase
When the phase to CW is more than 90 degree and the tag amplitude is large enough, the tag signal distorts drastically as shown below.
