A HANDHELD SPECTRUM ANALYZER OFFERING HIGH PERFORMANCE FROM A SMALL FOOTPRINT

摘要

The prime requirements of a handheld I spectrum analyzer are for it to be light-weight, compact, but with as large a display as possible, and exhibit low power consumption - all within a sturdy housing. These criteria are not easy to fulfill in themselves, so it is an even greater task to offer RF characteristics that are similar to those of desktop units. However, through large-scale integration and low power consumption of application-specific integrated circuits (ASIC), the FSH3 spectrum analyzer meets these requirements. In fact, the instrument uses six different ASICs to provide the functions of a top-class spectrum analyzer with an integrated tracking generator. The FSH3 handheld spectrum analyzer is available in two versions, either as a pure 100 kHz to 3 GHz spectrum analyzer or as a spec- trum analyzer with a tracking generator for scalar network analysis. Equipped with other options such as a power sensor and a VSWR bridge, it can be used as a power meter, a scalar network analyzer or an analyzer for distance-to-fault measurements on cables.
