Galli, G. and Lanza, M. and Salvato, G. (1992) An automatic apparatus for the dielectric spectra collection. Accademia Peloritana dei Pericolanti Casse FF.MM.NN., 70. pp. 83-91.
We describe an automatic apparatus for the measurement of dielectric spectra as a function of frequency (in the $10^0 \ - 10^5$ Hz range) and of temperature (from liquid He up to 500 K), The apparatus consists of a Personal Computer that controls a Lock-in Amplifier, a Signal Generator and an appropriately designed thermostat. Examples of measured spectra for salt complexed Poly(ethylene-Oxide) are also reported.
