Read the band, not just the deepest dipThe band reader linearly interpolates dB crossings between samples. A sweep boundary is not a confirmed resonance edge, and unsampled features remain unknown.Read the band, not just the deepest dipSchematic curve only; threshold and sample spacing are design inputs.Chosen thresholdInterpolated interval; repeat with finer samplesS11 dBFrequency³Ô¹Ïtv engineering illustration · conceptual, not to scale · no measured product data
