1)
For ¸FSH 3 model .23 with serial number 103500 or later.
2)
¸FSH-K2 required.
¸FSH standard function
Not available
The ¸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 measur-
ing 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.
