Analysis Type(s)
Image spur(s)
Single-tone
Interleaving image spurs caused by gain mismatch and aperture time delay mismatch of
Two-tone
the channels (power and frequency)
Offset spur
Single-tone
Interleaving offset spur caused by offset mismatch of the channels (power)
Two-tone
SFDR
Single.-tone
Spurious-Free Dynamic Range. Power relation between fundamental tone and largest
Two-tone
distortion. For a two-tone test, this is calculated as the relation between the largest
fundamental tone and the largest distortion. Frequency position of limiting component is
calculated.
SNDR
Single-tone
Signal-to-Noise and Distortion Ratio. Power relation between fundamental tone and noise
Two-tone
and distortion.
ENOB
Single-tone
Effective Number Of Bits. Based directly on the SNDR value.
Two-tone
