Reflection vs Transmission Accuracy in Vector Network Analyzer Measurement


Why is it that Reflection measurements are typically only specified to -35 dB? Meanwhile, Transmission measurements are valid to -85 or -90 dB or more. This is a common question and we get inquiries about this frequently. Brian Walker, Senior RF Design Engineer at Copper Mountain Technologies explores the reasons for this difference. Hopefully, this video will help clear up the contrast of Reflection and Transmission accuracy.
