[0036] In the present invention, the RFID test system host is installed with switch conversion software for allowing the tester to select the test mode from the software interface, such as Figure 2 shown.

[0037] The present invention has the following working principle:

[0038] See also Figure 1 When performing the RFID reader test, the tester selects reader test-reader on the switch conversion software. The signal sent by the RFID test system will be conducted to the COM port of the tag / reader test selection switch, and then the signal will be conducted to the CH1 port of the tag / reader test selection switch. The signal is input from the IN port of the reader test routing box, and after passing through the inside of the reader test routing box, it is conducted to the Tx / Rx port output, and then output to the Reader Test port on the front panel 7 of the RFID test system cabinet. The Reader Test port is connected to the reader under test, so that the signal is sent to the reader under test. The signal returned from the reader under test is received by the Tx / Rx port of the reader test routing box, and the signal is conducted to the OUT port after passing through the inside of the reader test routing box, and then output to the CH7B port of the tag test type selection switch. The signal reaching the tag test type selection switch is conducted to the COMB port, and then output to the IN port of the RFID test system. The RFID test system analyzes the signal returned by the reader to complete the reader test.

[0039] See also Figure 1When performing the RFID tag performance test, the tester selects the tag test-dual antenna on the switch conversion software. The signal sent by the RFID test system will be conducted to the COM port of the tag / reader test selection switch, and then the signal will be conducted to the CH0 port of the tag / reader test selection switch, and then output to the COM A port of the tag test type selection switch. Then the signal will be conducted to the CH4A port, and the signal will be directly output to the RF interface f (transmitter) of the full anechoic chamber antenna interface. The RF interface f (transmitter) of the full anechoic chamber antenna interface is connected to the transmitting antenna, and the signal can be sent to the tag under test through the air interface. The signal returned from the tag under test is received by the receiving antenna connected to the RF interface e (receiver) of the full anechoic chamber antenna interface through the air interface, and then output to the CH5B port of the tag test type selection switch. The signal reaching the tag test type selection switch is conducted to the COMB port, and then output to the IN port of the RFID test system. The RFID test system analyzes the signal returned by the tag to complete the tag performance test.

[0040] See also Figure 1 When performing RFID tag consistency test, the tester selects Tag Test-Front Panel on the switch conversion software. The signal sent by the RFID test system will be conducted to the COM port of the tag / reader test selection switch, and then the signal will be conducted to the CH0 port of the tag / reader test selection switch, and then output to the COMA port of the tag test type selection switch. Then the signal will be conducted to the CH6A port, and then output to the OUT (Tag Test) port on the front panel of the RFID test system cabinet. The OUT (Tag Test) port is connected to a dipole antenna, and the dipole antenna sends the signal to the tag under test through the air interface. The signal returned from the tag under test is received by another dipole antenna connected to the IN (Tag Test) port on the front panel through the air interface, and then output to the CH6B port of the tag test type selection switch. The signal reaching the tag test type selection switch is conducted to the COMB port, and then output to the IN port of the RFID test system. The RFID test system analyzes the signal returned by the tag to complete the tag consistency test.

[0041] See also Figure 1When conducting the RFID tag T IPP test, the tester selects the tag test-single antenna one, single antenna two, single antenna three, single antenna four on the switch conversion software. The signal sent by the RFID test system will be conducted to the COM port of the tag / reader test selection switch, and then the signal will be conducted to the CH0 port of the tag / reader test selection switch, and then output to the COM A port of the tag test type selection switch, and then the signal will be conducted to the four ports of CH0A, CH1A, CH2A, and CH3A, and the signal will be output to the four ports of I N1, I N2, I N3, and I N4 of the tag test routing box. After passing through the inside of the tag test routing box, the signal is conducted to the four ports of ANT1, ANT2, ANT3, and ANT4, and then output to the RF interface a, RF interface b, RF interface c, and RF interface d of the full anechoic chamber. The RF interface a, RF interface b, RF interface c, and RF interface d of the full anechoic chamber are respectively connected to the four antennas of the transceiver, and the signal can be sent to the tag under test through the air interface. The signal returned from the tested tag is received by four antennas through the air interface, and then output to the ANT1, ANT2, ANT3 and ANT4 ports of the tag test routing box through the RF interface a, RF interface b, RF interface c and RF interface d of the full radio wave darkroom. After passing through the inside of the tag test routing box, the signal is conducted to the OUT1, OUT2, OUT3, OUT4 ports, and then output to the CH0B, CH1B, CH2B, CH3B ports of the tag test type selection switch. The signal reaching the tag test type selection switch is conducted to the COMB port, and then output to the IN port of the RFID test system. The RFID test system analyzes the signal returned by the tag to complete the tag T IPP test.
