摘　　要：采用理论分析和实验相结合的方法,从测试精度和效率两个方面对冷态噪声测试法、两倍功率法和Y因子法进行了比较分析。结果表明,在网络分析仪上,冷态噪声测试法比其他方法更适用于研发所需的高精度测试和生产所需的高效率测试。介绍了减少测试误差的措施。Based on theoretical analysis and experiment, a comparative analysis was made on cold source method, twice-power method and Y-factor method, with respect to test accuracy and efficiency. Results showed that the cold source method on network analyzer could better satisfy demands of high-precision and high-efficiency test for both R ＆ D and mass production. Moreover, advices and suggestions were made about choosing the right method or technique to improve test accuracy and reduce test errors.
