Sometimes the RF reflection measurement that needs to be made is on the end of a lossy coaxial cable. How can you make a measurement on a long lossy cable and get accurate results for the device under test? Is it even possible? The answer is: maybe. The best answer is to eliminate the cable altogether and move the measurement directly to the DUT. You can make measurements on a hard-to-reach DUT easily with a handheld, 1-Port VNA from Copper Mountain Technologies. Watch this video with the mathematical explanation behind this reasoning and learn about the best options for this measurement.
