To ascertain the accuracy and consistency of Cadwell Spectrum 32, this paper performed the following tests: inputting a calibration signal and measuring the resultant amplitudes for quantitative electroencephalographs (qEEGs) and evoked potentials (EPs) in the mapping and standard montages, inputting a synchronous calibration signal and mapping it at varying times for qEEGs and Eps, as well as re-analysing the same electroencephalographic (EEG) epochs previously selected from 20 control subjects. Some of the accuracy and consistency limits of the hard- and software of the system with respect to the quantitative and topographic data were established. It is concluded that the systems need to be calibration-checked in the laboratories in which they are used, with an independent signal generator.
