Rohde & Schwarz FSH4 Handheld Spectrum Analyser Description
The Rohde & Schwarz FSH4 spectrum analyser 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.
The R&S FSH4 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, radio communications and service, measuring electric field strength or in simple lab applications. The R&S FSH4 can perform any of these tasks quickly, reliably and with high measurement accuracy.
Weighing only 3 kg, the R&S FSH4 is a handy instrument. All frequently used functions have their own function keys and are within fingertip reach. The brilliant colour 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 FSH4 battery enables uninterrupted operation for up to 4.5 hours. The battery is changed within seconds and all connectors are splash-proof.
Rohde & Schwarz FSH4 Key Features
- Frequency range from 9 kHz to 3.6 GHz
- High sensitivity (< –141 dBm (1 Hz)), with preamplifier < –161 dBm (1 Hz)
- 20 MHz demodulation bandwidth for analysing 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 analyser
- 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)
