RIFLECTOMETER

TV/CATV SPECIAL FUNCTIONS
In TV mode press the “HOME” key.
Touch “SPECIAL FUNCT”
and then “REFLECTOMETER”.
Touch “MENU” and set the features
of the coaxial cable you need to analyze
(see next page), at the end touch “EXIT”.
The instrument, equipped with “SW RIFLECTOMETER App”, allows you to check the correct
impedance matching of a 75
Ω
distribution installation.
Through the use of calibrated noise generator (for Example ROVER mod. CNG 90 STC/CNG 70
USB), if in a distribution installation there was an impedance mismatch, such as a cable short-
circuit, a cable cut or a not properly terminated cable to a 75 ohm dummy load, it will create
a standing wave pattern that can be seen on the spectrum of the instrument as shown in the
figures below.
