#37: Use a scope to measure the length and impedance of coax
Why people recommend it
Shows how to measure a cable's characteristic impedance with an oscilloscope using time domain reflectometry, often cited when transmission line questions come up.
Watch for: Needs a scope and a fast-edge pulse source to follow along
In their words
Do some time domain reflectometry, a useful video to this process is probably one from w2aew.
