How to Optimize Lossy Long Cable Measurements with a Vector Network Analyzer

Sometimes the RF reflection measurement which 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.
