Re: 50 ohm or 75 ohm?

Barbara, Why not. Site Masters have been successfully using in Telecommunication industry to maintain cable/antenna systems for years. Many antenna manufacturers are also using Site Masters in their R D and productions. The device can be roughly viewed as a simplified Vector Network

Hi Leslie, You may try a very convenient hand-held RF analyzer, Site Master (http://www.global.anritsu.com/products/test/rfmicrowireless/s100_s200a_s300 a.html), to determine whether the cable is 50 or 75 ohm. The price of Site Master is much less than Time Domain Reflector. Barry Ma

Leslie, This is fairly simple using an RF signal generator and an oscilloscope terminated at 50 ohms. The RF generator must have an output impedance of 50 ohms. The trick is to first measure the amplitude delivered at the oscilloscope from a known 50 ohm cable at 5 MHz or greater. Then, without
