Product data sheet
Effective bits are obtained via a Fast Fourier Transform (FFT) treatment taking 8000 acquisition points per equivalent fundamental
period. The calculation takes into account all harmonics and noise up to half of the clock frequency (Nyquist frequency). Conversion to
signal-to-noise ratio: SINAD = ENOB
Intermodulation measured relative to either tone with analog input frequencies of 4.43 MHz and 4.53 MHz. The two input signals have
the same amplitude and the total amplitude of both signals provides full-scale to the converter.
Measurement carried out using video analyzer VM700A, where the video analog signal is reconstructed through a digital-to-analog
converter.
