同軸の試験で長さが表示されない - CableIQ

If you have a 75 Ohm terminator at the end of your coax link, length will not be reported, since there is no reflection coming from the end of the link.

If you are testing a coax link with the CableIQ Terminator at the end of the coax link as shown below, you should expect a length reading. If you do not, please update your CableIQ to Version 1.3. This should resolve any length reporting issues on your coax links.
