Scalar transmission and reflection measurements

with VSWR bridge

The ¸FSH with built-in tracking generator rapidly determines the

transmission characteristics of cables, filters, amplifiers, etc, with a

minimum of effort. When equipped with the ¸FSH-Z2/-Z3 VSWR bridge

(10 MHz to 3 GHz/6 GHz), the ¸FSH can also measure the matching (return loss,

reflection coefficient, or VSWR) of an antenna, for example. The bridge is screwconnected

directly to the ¸FSH’s RF input and tracking generator output

without involving cumbersome, extra cabling. The innovative design of the

¸FSH-Z3 VSWR bridge with integrated RF bypass switch allows the user

to make spectrum and transmission measurements also with the bridge

connected. Active components such as amplifiers can be supplied directly via

the RF cable by means of the two integrated bias tees.
