摘要
针对在测试短波接收机的性能指标时,需使用的测试仪器种类繁多、操作复杂等不足,开发了一种便携式自动测试平台。介绍了在测试平台中实现多种调制模式的射频信号以及对音频信号进行采集分析的方法,测试结果对比使用综测仪测试,误差<0.1%,满足测试指标要求。
A portable automatic test platform for short wave receivers is developed to save the need for various test instruments and complicated operations. This modulation RF signals production and analysis audio signal on this test platform are described. The test results show that the error is less than 0. 1% , which meets the needs of test indicators of short wave receivers.
