FSH20

The R&S®FSH20 spectrum analyzer is rugged, handy and designed for use in the field. Its low weight, its simple, well-conceived operation concept and the large number of measurement functions make it an indispensable tool for anyone who needs an efficient measuring instrument for outdoor work.

Key Facts
• Frequency range from 9 kHz to 20 GHz
• High sensitivity (< -141 dBm (1 Hz), with preamplifier < -161 dBm (1 Hz))
• 20 MHz demodulation bandwidth for analyzing LTE signals
• Low measurement uncertainty (< 1 dB)
• Measurement functions for all important measurement tasks related to the startup and maintenance of transmitter systems
• Internal tracking generator and VSWR bridge with built-in DC voltage supply (bias)
• Two-port network analyzer
• Rugged, splash-proof housing for rough work in the field
• Easy handling due to low weight (3 kg with battery) and easy-to-reach function keys
• Easy operation thanks to user configurable, automatic test sequences (wizard)

Characteristics
The R&S®FSH20 is a spectrum analyzer and - depending on the model and the options installed - a power meter, a cable and antenna tester and a two-port vector network analyzer. It provides the three most important RF analysis functions that an RF service technician or an installation and maintenance team needs to solve daily routine measurement tasks. For example, it can be used for maintaining or installing transmitter systems, checking cables and antennas, assessing signal quality in broadcasting, radiocommunications and service, measuring electric field strength or in simple lab applications. The R&S®FSH20 can perform any of these tasks quickly, reliably and with high measurement accuracy.
