3.6 GHz Handheld Spectrum Analyzer
The new R&S FSH4/8 builds upon successes of FSH3/6/18 with network operators, TV broadcast operators, and military to offer an indispensable tool for field users who need an efficient measuring instrument. The new FSH4/8 improved upon RF performance, CPU speed, display size, interfaces for memory expansion slot to further support a very wide range of applications, and truly make it a mobile precise measurement instrument. Depending upon model and installed options, it serves as a power meter, cable and antenna tester, or a two-part vector network analyzer. With the new and improved GUI and dedicated function keys, it provides better operation to field users.
