Non-linear effects and the use of network analyzer time domain

While normally considered a tool for evaluating passive networks, vector network analyzer time domain can sometimes be of interest for active and semi-linear device analysis. The identification of sequential match compression in a multi-stage structure and the analysis of bias network-related delay anomalies are among the diagnostics available. The approach is not without its hazards, however, as defect shielding effects become more complicated and the VNA´s own compression behavior can be critical. The effects of these behaviors will be analyzed semi-quantitatively and a number of example measurements will be presented.
