Time Domain Network Analysis using the Multiline TRL Calibration

We apply the multiline TRL (through-reflect-line) method to the calibration of a time domain network analyzer (TDNA). The calibration removes the effects of cables and connectors, nonideal source and sampler responses, source and sampler mismatch, and frequency-dependent characteristic impedance of the transmission lines. Multiline TRL is especially well suited to TDNA and provides not only a complete calibration but also a full characterization of the transmission lines, information useful in the study of interconnections.
