In the far-field measurement system, using a network analyzer and amplifier mode for system measurement, the advantages can be achieved multi-frequency test, in conjunction with multi-port coaxial switches, enabling multi-port auto-test, without human intervention, with a high degree of automation, high test efficiency, easy operation and so on. And the use of amplifiers improves system dynamic range, achieve better test results. Using a network analyzer and amplifier mode can ensure greater efficiency of the test on the basis of test accuracy.
