CEEFAX: Measurement techniques
Abstract
Techniques were developed to measure the characteristics of a CEEFAX waveform and to assess the performance of a CEEFAX installation. Methods are discussed for measuring the normal CEEFAX waveform in terms of its level and other factors which affect the CEEFAX service at a receiving installation. Techniques are also described for assessing the CEEFAX performance of signal paths, using special test signals.
