Overview
Rohde & Schwarz FSH6 Handheld spectrum analyzer 100 kHz - 6 GHz, RBW 100 Hz -1 MHz, LCD color display, preamplifier
The Rohde & Schwarz FSH6 spectrum analyzer is a wide band, very sensitive receiver. It works on the principle of "super-heterodyne receiver" to convert higher frequencies (normally ranging up to several 10s of GHz) to measurable quantities. The received frequency spectrum is slowly swept through a range of pre-selected frequencies, converting the selected frequency to a measurable DC level (usually logarithmic scale), and displaying the same on the CRT of the Rohde & Schwarz FSH6. The CRT displays received signal strength (y-axis) against frequency ( x-axis).
Some applications for Rohde & Schwarz FSH6 Spectrum Analyzers include Site Monitoring: Verify that the frequency and signal strength of your transmitter is accurate. Interference: Before a system is installed you use a Rohde & Schwarz FSH6 spectrum analyzer to verify that the frequencies (you plan to use) are not occupied or if the presence of a very strong signal will interfere with your new setup. Interference can be created by a number of different situations. Other tests that utilize the Rohde & Schwarz FSH6 spectrum analyzer features include antenna isolation, co-channel interference, adjacent channel power, occupied bandwidth, intermodulation, microwave or satellite antenna alignment, and characterization of components.
The FSH is the ideal spectrum analyzer for rapid, high-precision, cost-effective signal investigations. It provides a large number of measurement functions and so can handle anything from the installation or maintenance of a mobile radio base station up to on-site fault location in RF cables as well as development and service -an extensive range of applications. Due to its excellent characteristics, the FSH is used on board the International Space Station (ISS) for distance-to-fault measurements on RF antenna cables.
