3 Acronyms, Abbreviations and Definitions
3.1 Acronyms and Abbreviations
PXIe : PXI Express.
SNR: Signal-to-Noise Ratio. It is expressed in dBs. It is defined as the ratio of a signal
power to the noise power corrupting the signal.
SINAD: Signal-to-Noise Ratio plus Distorsion. Same as SNR but includes harmonics
too (no DC component).
ENOB: Effective Number Of Bits. This is an alternative way of defining the Signal-to-
Noise Ratio and Distorsion Ratio (or SINAD). This means that the ADC is equivalent
to a perfect ADC of ENOB number of bits.
SFDR: Spurious-Free Dynamic Range. It indicates in dB the ratio between the powers
of the converted main signal and the greatest undesired spur.
