Abstract
Description
Technical Field
[0001] This utility model relates to a multi-port barcode scanning test system. Background Technology
[0002] A vector network analyzer is an instrument that measures the network characteristics of a device by measuring the amplitude and phase response of each port of the network to a frequency / power scan test signal. It combines various technologies such as spectrum analysis, signal generation, and signal separation, and is an essential test and measurement instrument in the field of radio frequency and microwave, as well as the basic form of many industry-specific instruments.
[0003] Currently available vector network analyzers can only perform scanning tests on two groups of antennas under test. When a large number of antennas with different specifications and frequencies need to be measured to determine their quality, multiple vector network analyzers must be used, and the overall purchase cost of vector network analyzers is expensive.
[0004] Therefore, how to perform quality testing on a large number of antennas with different specifications and frequencies using a single vector network analyzer is a problem that relevant technical personnel need to consider and solve. Utility Model Content

[0007] Preferably, it further includes a second switch, which includes 12 input ports and an output port for connecting to the server.
[0008] Preferably, the system further includes a plurality of packaging computers, each of which is packaged by the server for the antenna that has a good detection result.

[0010] Due to the adoption of the above technical solution, this utility model has the following beneficial effects:
[0011] Up to 12 test computers can be connected at once through the switch, and the antenna specifications of up to 12 groups of antennas under test can be stored to the server. The vector network analyzer can then sequentially test the antenna properties of the 12 groups of antennas under test, thereby effectively increasing the number of antennas that can be tested. Previously, the vector network analyzer could only test 2 groups at a time, but now it can test 12 groups at once. Attached Figure Description

[0016] Please refer to Figure 1 and Figure 2 The diagram shows the application configuration of the test computer and the packaging computer of the multi-port barcode scanning test system of this utility model.
[0017] This utility model is a multi-port barcode scanning test system, mainly including: server 1, first switch 2, test computer 3, switcher 4, and vector network analyzer 5. The first switch 2 includes 12 input connection ports 20 and output connection ports 22. The output connection ports 22 are connected to server 1. The 12 input connection ports 20 of the first switch 2 are each connected to the test computer 3. The first switch 2 controls each test computer 3. Each test computer 3 scans the detection specification information code on the antenna under test to obtain the antenna specification frequency (2.5G or 5G) and voltage standing wave ratio (VSWR) of the antenna under test. The data is then included in the test schedule according to the scanning order and stored in server 1. Specifically, when the test computer 3 performing the barcode scanning is in the order of the 1st, 4th, and 7th test computers, the scanned antenna specifications will be stored in server 1 in the order of the 1st, 4th, and 7th test computers.
[0018] The vector network analyzer 5 is equipped with two analyzer input ports 50, each of which is connected to the switcher output port 40 in the switcher 4. The switcher 4 is also equipped with six switcher input ports 42. Each switcher 4 can switch the antenna to be tested, and the vector network analyzer 5 obtains the antenna properties of each antenna under test. At the same time, the server 1 obtains the antenna specifications corresponding to the antenna under test, performs antenna characteristic testing, and generates a test result that can distinguish whether the antenna characteristics are good or not, and then stores it in the server 1.
[0019] After completing the antenna characteristic detection, analysis, and storage, the good antennas can be packaged through a second switch 6 and multiple packaging computers 7 during shipment. The second switch 6 mentioned above includes 12 input ports 60 and output ports 62. The 12 input ports 60 can be individually connected to the packaging computers 7, and the number of connections can be determined according to the needs. The output ports 62 are connected to the server 1. Each packaging computer 7 is packaged by the server 1 for antennas with good detection results.
[0020] As can be seen from the above, this utility model allows 12 test computers 3 to be connected at one time through the first switch 2, and can store the antenna specifications of up to 12 groups of antennas under test to the server 1. The vector network analyzer 5 can then sequentially test the antenna properties of the 12 groups of antennas under test, thereby effectively increasing the number of antennas that can be tested. This allows the vector network analyzer 5, which could previously only test 2 groups at a time, to test 12 groups at once.
