Error vector-based measurement procedures for RF digital transmitters troubleshooting

摘要: The rapid growth of modern telecommunications systems has created the need getting new test equipment as well measurement techniques up and running in a very short time. With particular regard to transmitters troubleshooting, methods procedures are clearly claimed for, because those based on analysis constellation diagrams, currently supported by major manufacturers, show some intrinsic limitations. Some original straightforward procedure, use error vector (EV), which overcome aforementioned limitations, proposed paper. They addressed I/Q section transmitters, particularly affective both terms accuracy time when only one or two impairments significant. Besides providing an analytical description, paper gives details extended experimental campaign carried out actual telecommunication signals order assess performance procedures.
