RFID read / write test

The RFID read/write test by using Anechoic box,signal analyzer and Programmable attenuator


object : slight wireless / 900MHz UHF band of RFID


[Problem and solution]

  1. The measurement value from antenna displayed on a signal analyzer changes at each measurement
    => The measurement value becomes stable when the outside noise is cut off more than 60dB.
  2. The strong reflection occurs in the shield box
    => The reflection decreases when it is absorbed more than 10dB by the radio wave absorber.
  3. Fresnel zone is measured at the correct distance in the anechoic box
    => The measured data is almost same as in a chamber.
  4. The handover test and the carrier sense level can be simulated by using the programmable attenuator together.

Usage example:
slight wireless / 900MHz UHF band of RFID (Fresnel zone 35cm ellipse)
