Advantest U3751
Spectrum Analyzer 9kHz to 8GHz
Description
The U3751 8 GHz Portable Spectrum Analyzer equally suitable for use on wireless communication device production lines and for field uses such as electromagnetic environment testing. The main unit weighs 5.6 kgs. or less and is designed to save space. The U3751 is twice as fast as its predecessor and is equipped with features such as LAN, designed specifically for the production line. Digitization of the IF section has enabled level measurements with outstanding reproducibility.
With a three-way power supply that includes battery operation,
better level accuracy, and a warm-up time of five minutes, this analyzer is easy to use in the field.
The U3751 includes basic spectrum analyzer measurement functions and options such as an internal tracking generator. All of these features combine to make the U3571 a portable spectrum analyzer for both factory and field use.
