LOW-DISTORTION HARMONIC SIGNAL QUALITY TESTING

Vaclav Papez, Stanislava Papezova

Abstract

The main problem of the high resolution ADC testing within the frequency range hundreds of kHz to tens MHz is the spectral purity of testing signal. Commercially produced low-distortion generators have the spectral purity sufficient for testing of ADC app. up to 16 bit, analogous to sensitivity of commercial analyzers for measuring of signal quality is enough for check of signal with of signal spectral purity for testing of ADC app. up to 16 bit. There is necessary to use special methods for measuring of special signal sources with extreme high spectral purity that are designed with higher resolution for ADC testing. These methods make possible to extend dynamic range and to increase sensitivity of signal analyzers, in order to analyze test signal.
