Time-domain measurement of loss and dispersion
Abstract
Results are presented in the frequency range 0.4-10 GHz for transformed time-domain measurements of transmission line attenuation and dispersion for microstrip, RG/U 58, and RG/U 188A coaxial cable. Essentially, time-domain metrology (TDM) characterizes a component by its transient response to a subnanosecond baseband pulse. Good agreement is found between measured, computed, and published data. A major advantage of TDM in transmission line testing is that unwanted responses can be excluded from the measurement time window. Because of the time separation between multiple returns, errors due to interface discontinuities can be evaluated and removed from the final data.
