RFID read / write test
The RFID read/write test by using Anechoic box,signal analyzer and Programmable attenuator
- The various radio waves flit in the office and the factory. (PC, Server, Wireless LAN and etc.)
- The radio waves of a public wireless and being used in other offices enter from the outside. (Cellular phone, Wireless LAN and PHS)
- If the DUT (device under test) is measured in the anechoic box, the correct data can be gotten because outside noise is inteercepted and internal radio wave is absorbed.
- The programmable attenuator with the frequency range from 750MHz to 13.5GHz enables the simulation of the receiving sensitivity.

[Problem and solution]
- 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.
- The strong reflection occurs in the shield box
=> The reflection decreases when it is absorbed more than 10dB by the radio wave absorber.
- Fresnel zone is measured at the correct distance in the anechoic box
=> The measured data is almost same as in a chamber.
- The handover test and the carrier sense level can be simulated by using the programmable attenuator together.
