Universal testing method for broad band product interface single board

Abstract

A wide a band product interface single plate general test method based on a system containing host test device of providing data source, analyzing and receiving data includes the following steps: connecting the tested interface plate to a general bus interface of the testing device via n interface bus converting module; controlled by the host, CPU initializes the tested interface plate, matches and sends tested data and circulates back via tested interface plate, processes received data; CPU fetches the above mentioned test result and statistic information to the testing host.

Description

technical field [0001] The invention belongs to the communication equipment testing technology, in particular to a universal testing method for interface single boards of broadband products. Background technique [0002] With the development of communication technology, there are more and more types of interface boards for broadband products, and the speed is getting faster and faster. Therefore, higher requirements are put forward for the testing of such boards. [0003] The interface type single board is generally simple in structure, mainly realizes the physical layer function of the communication network, and provides the service interface with the link layer. The composition of general broadband interface boards is as follows: figure 1 shown. It is mainly composed of physical layer processing chips, link layer interfaces, optical and electrical interfaces, and serial-to-parallel conversion units. [0004] Broadband interface boards are always connected to the transce...

AI Technical Summary

Problems solved by technology

There are many types of interface boards, and it is difficult for a general tester to provide all the docking interfaces. Therefore, a variety of different testers are often required in the test, which is not conducive to system integration in addition to increasing costs.

The speed of the interface board is getting higher and higher. The past experience is that the development of the tester cannot keep up with the development of broadband products, so there may be situations where the tester cannot meet the test (even simple performance test and functional test).

[0008] Using the above scheme 2, the normal situation is that the full rate test cannot be achieved, so the traffic processing capability of the physical layer cannot be tested.

Adding data sources, control sources, and clock sources at the link layer or higher layers often brings additional interference to complex systems

At the same time, for products that are eager to go to market, it will bring a lot of workload and affect the progress of going to market

In addition, the above two general methods have the problem of inflexible configuration
