N8519BM is a high-performance vector network analyzer with advanced performance and broad application fields. It can be used to measure the two-port network parameters in microwave frequency band and other frequency bands. This article will introduce the application fields and working principles of this vector network analyzer.The N8519BM is mainly used in RF and microwave transceiver design, Antenna measurement, RF plug and connector manufacturing, RF and microwave assembly system and S parameter testing.In RF and microwave transceiver design, the N8519BM can be used to measure the RF characteristics of amplifier, filter, antenna, duplexer and other components. In Antenna measurement, it can be used to measure the parameters of various antenna systems. In RF plug and connector manufacturing, it can be used to measure the parameters such as insertion loss, return loss, VSWR, etc. In RF and microwave assembly system, it can be used to make measurements of the entire system or a subsystem.The working principle of the N8519BM is mainly based on vector network analysis. Vector network analysis is a method for measuring the S parameters of an RF network. It uses the connection of the devices to form a vector network, and the vector network is connected to the vector network analyzer. The analyzer sends out a test signal, and measures the reflection coefficient, insertion loss, return loss, VSWR, and other parameters of the vector network.The key components of the N8519BM include a signal generator, a mixer, a power divider, a directional coupler, a power detector and other components. The signal generator is used to generate a test signal as input to the vector network, the mixer is used to mix the input signal with the output signal of the vector network, and the power divider is used to subdivide the signal into two parts. The directional coupler is used to measure the standing wave ratio, and the power detector is used to measure the power at the ports of the vector network.In summary, the N8519BM vector network analyzer has broad application fields and advanced performance. It can be used to measure the S parameters of a wide range of devices and can be used to measure the parameters in the microwave frequency band.
