Spurious-Free Dynamic Range (SFDR)

The ratio of the rms signal amplitude to the rms value of the

peak spurious spectral component. The peak spurious compo-

nent may or may not be a harmonic. May be reported in dBc

(degrades as signal level is lowered) or in dBFS (always related

back to converter full scale).

Two-Tone Intermodulation Distortion Rejection

The ratio of the rms value of either input tone (f1, f2) to the rms

value of the worst third-order intermodulation product;

reported in dBc. Products are located at 2f1 − f2 and 2f2 − f1.

Two-Tone SFDR

The ratio of the rms value of either input tone (f1, f2) to the rms

value of the peak spurious component. The peak spurious com-

ponent may or may not be an IMD product. May be reported in

dBc (degrades as signal level is lowered) or in dBFS (always

related back to converter full scale).

Worst Other Spur

The ratio of the rms signal amplitude to the rms value of the

worst spurious component (excluding the second-order and

third-order harmonic); reported in dBc.
