绝大部分的微波测试台都需要功率计。当频率高于100kHz 时,能可靠地反映出射频及微波信号幅度的不是电压或电流,而是功率。因此,这类测试仪器近年来发展甚快,目前,很多功率作为大型自动测试设备系统的一部分正发挥其功能。同时,不少功率计在不同的应 The vast majority of microwave test benches need power meters. When the frequency is higher than 100kHz, can reliably reflect the RF and microwave signal amplitude is not voltage or current, but power. As a result, these types of test instruments have developed rapidly in recent years and at present, a great deal of power is exerting its function as part of a large automated test equipment system. At the same time, many power meters should be different
