The R&S FSH is available as a 3 GHz or 6 GHz model either with or without an internal tracking generator. When the tracking generator is included, the ¸FSH can be used for distance-to-fault (DTF) measurements, scalar and vector network analysis, and one-port cable loss measurement. Almost all models come standard with an adjustable preamplifier, making them suitable for measuring very small signals. Power sensors are available as accessories for high-precision terminating power measurements up to 8 GHz or 18 GHz as well as for directional power measurements up to 4 GHz. The following tables show possible configurations for various applications and an overview of available models.
Electro Rent recommends the newer FSH Series with the FSH4/FSH8/FSH13/FSH20 models. Also see the FPH Series Handheld analyzer as well for a newer Series.
