Abstract: We comprehensively analyzed the technical indexes of typical function generators at home and abroad.According to the use of instrument functions and the degree of impact on test results,we comprehensively and systematically classified and graded the technical indexes based on functional indexes,performance indexes,and general quality characteristic indexes.And then we developed the research on testing methods and testing experiments.More importantly,we conducted in-depth analysis of various test results,which it not only provides experimental data support for instrument users and manufacturers,but also provides the suggestions for instrument function selection,optimal design,and performance status evaluation.

Key words: Technical indexes, Quality characteristic, Testing experiments, Optimal design, Performance status
