Abstract :
To accurately observe the characteristic, or behavior, of the PA, the test platform is required to have enough bandwidth and dynamic range. Digital processing techniques for extending the dynamic range and bandwidth of the measurement instruments are discussed. Test results show that employing such techniques can successfully build a test bed of high dynamic range and wide bandwidth.
