  • Network analyzer measurement method for high dynamic range devices
    Patent number: 6018246
    Abstract: A measurement method adjusts the IF bandwidth of a network analyzer to increase measurement speed for high dynamic range devices. According to the first preferred embodiment of the present invention, the bandwidth of the IF filter is adjusted for each corresponding measurement sweep of the network analyzer. The forward transmission and reflection characteristics of the device under test are measured using a first IF bandwidth, and the reverse transmission and reflection characteristics of the device are measured using a second IF bandwidth. When high measurement sensitivity of the forward transmission parameter of the high dynamic range device is sought, the first IF bandwidth is selected to be narrower than the second IF bandwidth. When high measurement sensitivity of the reverse transmission parameter of the high dynamic range device is sought, the first IF bandwidth is selected to be wider than the second IF bandwidth.
