Problems solved by technology

[0003] (1) Time-consuming and labor-intensive; manual debugging requires a lot of skilled debugging workers, and the length of debugging time depends on the debugging experience and even luck of the workers;
[0004] (2) Low production efficiency and high rate of defective products: Electronic components produced at home and abroad have precision errors. For radio frequency signals, small precision errors often lead to very large poor performance, which seriously exacerbates the difficulty and persistence of debugging and troubleshooting. time
In the actual situation, many times the manual debuggi

Embodiment 2

[0047] This embodiment is an automatic debugging method of the radio frequency signal product automatic debugging system in the first embodiment.

[0048] like Figure 3-1 and 3-2 As shown, the PC performs the following steps:

[0049] Step 1 Establish communication between the computer, the vector network analyzer and the product to be tested;

[0050] Step 2 Read in the RF signal channels and channels that need to be debugged this time, and look up the table to preset the frequency point, bandwidth, out-of-band signal suppression and signal gain indicators corresponding to each channel;

[0051] Step 3 Instruct the vector network analyzer to perform the channel performance index test, accept the performance index test data fed back by the vector network analyzer, and judge whether the test data meets the index requirements of the preset table; if it meets the index requirements, perform step 4; if it does not meet the index requirements, go to step 5;

[0052] Step 4 rea...

Abstract

The invention discloses an automatic debugging system for radio-frequency signal products, in which a product to be tested, a vector network analyzer and a computer are arranged, wherein the inside of the computer is provided with a preset table and debugging packets corresponding to each channel, the preset table is used for presetting the frequency point, bandwidth and OOB (out of band) signal curbing and signal gain factor indexes of each corresponding frequency channel within the radio-frequency signal range, and the frequency points in the preset table correspond to the frequency points of all frequency channels to be tested one by one; each channel has n debugging packets, each debugging packet contains groups of debugging control signals which are in a channel and correspond to each frequency channel, each group of debugging control signals refers to four analog voltages, and the four analog voltages are respectively used for debugging the frequency point, bandwidth and OOB (out of band) signal curbing and signal gain factor indexes of the debugging channel; and the computer is connected with the product to be tested by a communication bus, and connected with the vector network analyzer by an LAN line.

Description

technical field [0001] The invention belongs to the field of debugging control of radio frequency signal processing products, and in particular relates to an automatic debugging system of radio frequency signal products. Background technique [0002] At present, in the field of global radio frequency product production, how to quickly and effectively control mass production of radio frequency signal processing products (such as the adjustable bandpass filter in this article) to achieve good debugging results, such as a high proportion of performance standards and consistent products Good sex, etc., has always been an international problem. At present, relevant production and processing enterprises and research institutes at home and abroad all adopt the method of manual debugging: that is, to set performance indicators for the products, and then require the processing workers to use the vector network analyzer to initially test the product performance, and pass the part that...
