Description	Není k dispozici (cs) The main problem of the high resolution ADC testing within the frequency range hundreds of kHz to several MHz is the spectral purity of a testing signal. Commercially produced low-distortion generators have the spectral purity sufficient for testing of 16 bits ADCs only up to frequencies of tens of kHz; at higher frequencies the spectral purity of generators is generally worse. Some improvement can bring signal filtering. However, most of the LC filters use coils with ferromagnetic cores for the frequency range up to several hundreds of kHz, which can cause a rise of odd harmonic components. Nevertheless, these components can be measured and subtracted from the spectrum calculated from ADC output data. In the ideal case, only the frequency spectrum corresponding to the ADC non-linearity remains. An ADC measurement system was designed and built for the verification of this method in the frequency range 200 kHz to 1 MHz.
