Technical Field

[0001] The invention belongs to the technical field of data communication testing, and in particular relates to a data communication tester. Background Art

[0002] Data communication testing refers to testing whether the technical performance indicators of data circuits, data terminals and switches meet the relevant recommendations and requirements of CCITT;

[0003] With the development of modern data communication technology, various devices with data communication functions are becoming more and more complex. Correspondingly, the test data streams in the device data communication test are also becoming more and more complex, which leads to a significant reduction in the transmission speed of the test data stream, affecting the overall test efficiency.

[0004] In addition, the specific performance requirements of communication equipment may vary depending on the location of use or the receiving customers. For example, some customers require faster communication speeds, others require higher communication stability, and still others require less communication data loss. In the above cases, the test emphasis on the corresponding communication equipment is also different, so it is necessary to reconfigure the dedicated tester, which affects the versatility of the test process for the same equipment.
