Measuring Cable Insertion Loss - Klein 3000 Series Operation And Maintenance Manual

C.4.1 Measuring Cable Insertion Loss
To get an accurate assessment of your tow cable assembly, we suggest that you use
a Hewlett Packard 4194A Impedance/Gain-Phase Analyzer or similar.
A sample plot is shown in Figure C-3.

If you do not have access to a Hewlett Packard 4194A Impedance/Gain-Phase
Analyzer, you can get a close reading by using a function generator, a 50-ohm
terminator and an oscilloscope as shown in Figure C-4.
