| Abstract: | Measurement errors will be caused because of the time delay on the cable when you measure a long cable with the Vector Network Analyzer. In the paper we discuss the sources of measurement errors by analyzing the principle of VNA, solutions to increase measurement accuracy in different applieations is also given. |
