UHF RFID, also known as RAIN RFID, is on the rise in many different industries. While for the retail industry there are a thousand times more tags than readers, in some industries the phenomenon is the opposite. Particularly in the automotive industry and production, there is a strong need to improve reader accuracy and read rates due to the large number of readers.CISC RAIN RFID Xplorer is a solution that covers both laboratory and production test equipment, meeting the high requirements for reader sensitivity, individual phase and change insensitivity.

It is well known that the core component of the read-write equipment is the reader chip and antenna, the main function of the reader chip is to transmit and receive in accordance with the protocol. From the perspective of physical characteristics, the relationship between the transmit power and the receive sensitivity becomes very important, RFID Xplorer can connect the tag simulation module and the reader through the non-contact way, through the adjustment of the transmit power to detect the change of the receive sensitivity, but also can set the length of time to do a long time monitoring of the sensitivity stability. All these physical characteristics of the test are in accordance with ISO/IEC 18046-2 standard to carry out, while referring to the latest RAIN RFID RAIN Reader Sensitivity testing test method to read the EPC 90% pass rate of the receiving sensitivity point.

In addition to test the relationship between transmit power and sensitivity, BLF and receive sensitivity tolerance relationship test is reflected in the tag BLF change on the reader sensitivity impact. RFID Xplorer's tag simulation module can completely simulate the tag BLF change, change the BLF step to verify whether the reader has a tolerance defect.

In fact in the actual application reader antenna and label chip and other related key devices between the impedance match will also affect the sensitivity characteristics of the reader, CISC impedance simulator as a reader test equipment options can simulate the match imperfect antenna, these antenna may be due to production tolerances or changes in the surrounding RF environment. RFID Xplorer through software control to change its own Input impedance to complete, and can be in the impedance is not perfect in the case of evaluation of the reader characteristics. At the same time label signal phase change also has a great influence on the reader sensitivity, choose RFID Xplorer's phase shifter and reader tester with can simulate 0-360 degrees phase change to get different phase reader receiving sensitivity, which can be easier to improve the reader hardware design.

Several kinds of need test can combine to carry on, for example BLF, phase, impedance are all can do superposition test, this can in many dimensions to evaluate the read-write sensitivity whether there are defects.

When has completed all these does not have the configuration antenna read-write test, may install the different antenna which oneself prefers, carries on the read-write sensitivity non-connection test, sees whether can with the read-write initial design and the previous wired simulation antenna characteristic test the sensitivity matches.
                                                     

Therefore, to complete to assess the receiving sensitivity of a RAIN RFID reader, the first must be the need to follow the standard approved test methods and specifications, around Tx Power, BLF, phase, impedance matching and other directions to multi-dimensional verification of the sensitivity of the reader without antenna tolerance, confirm the wired test results and optimize the design can be designed or matched with the antenna to measure the sensitivity of Wireless receiving sensitivity characteristics.

In fact, these are the physical characteristics of the reader, many times software or firmware engineers will be more concerned about timing and instruction statistics related data, RFID Xplorer listener has reader instruction trigger, instruction analysis, advanced instruction statistics function, is particularly suitable for software engineers to analyze software problems tools.
