Insertion Phase Errors in Long Lengths of Coaxial Cable Assemblies

If you have ever tried to measure a long length of cable, you may have noticed the insertion loss (S₂₁,S₁₂) display showing an abrupt change at some frequency in the negative direction or scale. I call this change in transmission loss “cliffing” as if you were looking down a cliff. If not corrected during the calibration stage, this additional loss would add to the total system loss which is erroneous to the actual insertion loss of the cable assembly.Click to read more

Improving the accuracy of your microwave test and measurement equipment becomes increasingly important when high frequency devices are used in the transmission paths of radio, cellular, satellite and digital communications. This discussion helps to solve problems with measurement errors during and after calibration of your microwave test instrument. Click to read more
