U3751 is a portable 8GHz spectrum analyzer that can be used for maintenance and installation of digital product production lines, cable TV and wireless local area networks, and a wide range of other purposes. U3751 has a high-speed data throughput rate, twice that of the conventional Advantest model. This provides a guarantee for reducing operation time and production line applications, and has a limited pass/fail discrimination mode.
Due to its digital interface, U3751 has very strong repeatability in power measurement, with a level accuracy of<± 0.8db.
In addition, U3751 uses batteries during operation and only requires five minutes of preheating, making it suitable for outdoor and field testing.
