REFLECTOMETER (OPT.)

________________________________________________

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 REFLECTOMETER App”, allows you to check the correct
impedance matching of a 75 Ω distribution installation.

Through the use of calibrated noise generator, 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.

NOTE:

The special functions depend

on the active operating mode: TV SAT
or CATV
