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.

Field users can efficiently use and effectively address the following applications using the new R&S®FSH4/8:

• Service & Maintenance on transmitter stations
• Cable & Antenna tests
• EMF measurements
• EMI precompliance
• Signal monitoring
• Interference hunting
