The R&S FSH20.20 20 GHz Handheld Spectrum Analyzer with preamplifier is rugged, handy and designed for use in the field. Its low weight and large number of measurement functions make it an indispensable tool for anyone who needs an efficient measuring instrument for outdoor work. 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. The FSH20.20 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. Specifications. Frequency range: 9 kHz to 20 GHz. Frequency resolution: 1 Hz. Frequency readout Marker resolution: 0.1 Hz. Marker resolution Uncertainty: ±(marker frequency × reference uncertainty + 10 % × resolution bandwidth + 1/2 (span/(sweep points – 1) + 1 Hz). Frequency span: 0 Hz, 10 Hz to 20 GHz. Sweep time: 200 µs to 100 s (span = 0 Hz), 20 ms to 1000 s (10 Hz <= span <= 600 MHz), 20 ms × span/600 MHz to 1000 s (span > 600 MHz). Resolution bandwidth Range: –3 dB bandwidth 1 Hz to 3 MHz in 1/3 sequence; zero span, 10 MHz, 20 MHz additionally. Display range: displayed noise floor to +30 dBm. CW RF power: 30 dBm (= 1 W).
