Cable impedance meter.

Check out the e4990a impedance analyzer 20 hz to 120 mhz with flexible frequency options. Category 5 cable cat 5 is a twisted pair cable for computer networks since 2001 the variant commonly in use is the category 5e specification cat 5e the cable standard provides performance of up to 100 mhz and is suitable for most varieties of ethernet over twisted pair up to 1000base t gigabit ethernet. You need an accurate unit with four wire measurement capability which in my case is an excellent and cheap der ee de 5000 handheld lcr meter. We strive to deliver complete solutions to meet your needs from lcr meter impedance meter to a wide variety of test accessories.

Cat 5 is also used to carry other signals such as telephony and video. Looking for the next generation of impedance meter. But how do you get the inductance and capacitance of your bit of cable. An easy way to see the impedance of a cable is to apply a square wave signal to a cable of about 10 meters 30 feet on the end of the cable a pot from about 100 ohm and connect it to a oscilloscope look at the square wave and adjust the pot until you have no overshoot and it look the most as the original signal.

Just take a piece of the cable just a short piece is enough and measure the capacitance between the center core lead and the shield of the cable on one end of it.
