Selection Guide

Altogether six R&S®FSH models for different applications and frequency ranges are available. The R&S®FSH4 and R&S®FSH8 can perform measurements up to an upper frequency limit of 3.6 GHz and 8 GHz, respectively. Models featuring a built-in tracking generator can also be used to determine the transmission characteristics of cables, filters, amplifiers, etc. Additional models with built-in tracking generator and internal VSWR bridge are available for distance-to-fault (DTF) measurements, matching measurements and vector network analysis. All models have an adjustable preamplifier, making them suitable for measuring very small signals. Two power sensors are available as accessories – for precise terminating power measurements up to 18 GHz and for directional power measurements up to 4 GHz. The following tables show possible configurations for different standard functions and applications as well as an overview of available models.
