Description

Technical Field

[0001] The utility model belongs to the field of high-throughput satellite terminal performance testing, and in particular relates to an automatic testing device. Background Art

[0002] In recent years, high-throughput satellite communication business has developed rapidly, the demand in the military and civilian fields has gradually increased, customer requirements have been continuously improved, and the contradiction between high quality and short construction period has gradually intensified. In the production process, the testing process is complicated, and there are problems such as low efficiency and high error rate of manual testing. People prefer to use automated testing equipment to reduce the operating difficulty of testers, improve the accuracy of product testing, and efficiently use the night time for unmanned operations. Therefore, automated equipment came into being.

[0003] The following is a detailed description of the existing schemes and their implementation:

[0004] First, let's introduce the object to be tested, which is a high-throughput satellite terminal. It is a circuit board with modulation and demodulation functions. One end of the circuit board has a DC power socket, three network ports, and two F-type radio heads. The DC power socket is connected to 24V direct current to power the entire circuit board. The three network ports are the management network port, business network port 1, and business network port 2. There are two F-type radio heads, one for transmitting radio frequency signals and the other for receiving radio frequency signals.

[0005] The test process of high-throughput satellite terminal is as follows: Figure 8 As shown in the figure, the testers are in place at each workstation according to the process flow and carry out the work according to the test rules. A large number of repetitive and complex operations need to be completed manually by the testers.

[0006] The shortcomings of the existing technology have gradually emerged:

[0007] 1. The probability of static electricity affecting products increases

[0008] Processes 7, 8, 9, 10, 15, 16, and 17 all require testers to take anti-static measures, power on and off each high-throughput satellite terminal, and touch the product too frequently, affecting electrostatic sensitive components.

[0009] 2. Staff fatigue affects product testing efficiency

[0010] During the RF test, testers test single carriers and modulated waves of different frequencies and powers, and also need to measure a series of parameters such as frequency stability, phase noise, adjacent channel leakage ratio, etc., which requires long-term and uninterrupted operation of the spectrum analyzer. Testers are prone to fatigue, which reduces test efficiency and increases the test error rate.

[0011] 3. The unstable state of the test RF cable affects the test results

[0012] In RF testing, long-term rotational connection of the RF line can easily cause damage to the RF line, resulting in inaccurate test results and affecting the actual performance of the product. Utility Model Content

[0013] In view of this, the utility model proposes a high-throughput satellite terminal test equipment based on an automated test production line (hereinafter referred to as "test equipment"), which optimizes the previous test method and Figure 8 The processes numbered 7-10 and 15-17 are replaced by the processes of automatic testing using the test equipment.

[0016] Furthermore, the SMB fixing seat is connected to the F radio frequency head of the high-throughput satellite terminal through the SMB head, which is converted from the SMB head to the SMA head and then from the SMA head to the F head.
