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 component

may or may not be a harmonic. May be reported in dBc (that is,

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

to converter full scale).

Two-Tone Intermodulation Distortion Rejection

The ratio of the rms value of either input tone to the rms value

of the worst third-order intermodulation product, reported in dBc.

Two-Tone SFDR

The ratio of the rms value of either input tone to the rms value

of the peak spurious component. The peak spurious component

may or may not be an IMD product, and may be reported in

dBc (that is, 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 and third

harmonics), reported in dBc.
