WebFeb 21, 2024 · It is referring to the transmission line impedance. A twisted pair is a balanced line. Google transmission line for more information. It takes into account that both wires are the transmission line. 120 ohms is pretty common for twisted pairs. I'm surprised that your link specs 75 ohms. – lakeweb Feb 20, 2024 at 23:42 WebZSC is the Short Circuit Impedance To measure a coaxial cable (in the frequency range 10 Hz to 2 MHz) on the IET Labs 7600 Plus. 1. Connect the cable via 7000-03 leads or fixture to the 7600 front panel output terminals. 2. Perform OPEN / SHORT zeroing on the 7000-03 leads (or your fixture).
