2. Training Objective
Deliver knowledge that allow
you to run/save tests according
to client requirement to provide
a proof of quality for RF jumpers
and/or and antenna installed

11. Line sweeping
Measure the quality of a transmission
and/or antenna
Measure line loses and locate faults

13. Return Loss

14. Return Loss/VSWR

15. Return Loss/VSWR
RF components

16. Insertion Loss
• How much output signal is smaller in respect
signal?
RF energy lost (heat and leakage)
Why are we using these 7/8” cables
to input
•
•
Larger diameter coaxial cable for higher frequencies and
longer runs

17. Necessary
Frequency range
Cable type(s)
Distance of cable run
