AT A GLANCE The R&S®FSH 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. Weighing only 3 kg, the R&S®FSH is a handy instrument. All frequently used functions have their own function keys and are at your fingertips. The brilliant color display is easy to read even under poor lighting conditions, and it has a monochrome mode for extreme conditions. The capacity of the R&S®FSH battery enables uninterrupted operation for up to 4.5 hours. The battery can be changed within seconds and all connectors are splash-proof. The R&S®FSH is a handheld 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 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®FSH can perform any of these tasks quickly, reliably and with high measurement accurac

Analysis of NB-IoT transmit signals The R&S®FSH-K56 option enables the R&S®FSH to mea - sure NB-IoT transmit signals. NB-IoT occupies a band - width of 180 kHz or one resource block in LTE transmis - sions. The error vector magnitude (EVM) and frequency error shown on the result summary page are important parameters for determining the quality of the transmitted signal. Other NB-IoT downlink physical signal parameters (NPSS, NSSS and NPBCH) are also measured and dis - played. The constellation diagram graphically shows the quality of the NB-IoT signals. The R&S®FSH-K56 option supports analysis of an NB-IoT downlink signal in three deployment modes - in-band, guard band and standalone
