Abstract:
The new time domain measurement system for dielectric measurements is
described. The current model is comprised of an IBM PC-AT/486,
`'TDM-2,'' a new time domain measurement system, a set of
thermostabilized sample holders, and operation and analysis software.
This system is designed for use in the measurement of dielectric
parameters of liquid and solid materials over the frequency range 100
kHz-10 GHz. Software consists of programs of registration, accumulation
and data collection, Fourier analysis, time domain treatment, analysis
software: fast and reliable nonlinear curve fitting programs to
determine spectroscopic parameters and correlation analysis in time
domain. The system utilizes the difference method of measurement with
the registration of primary signals with multiwindow nonuniform
sampling. Such a system permits the overlap of a frequency range of
five orders in a single measurement. (C) 1996 American Institute of
