Signal to Noise Ratio (SNR) is the ratio of a fundamental to
the noise floor of the analog output. The first 5 harmonics
are ignored, and an output filter of
used to eliminate alias products.
Total Harmonic Distortion (THD) is the ratio of the DAC
output fundamental to the RMS sum of the harmonics. The
first 5 harmonics are included, and an output filter of
clock frequency is used to eliminate alias products.
Spurious Free Dynamic Range (SFDR) is the amplitude
difference from a fundamental to the largest harmonically or
non-harmonically related spur. A sine wave is loaded into
the D/A and the output filtered at
eliminate noise from clocking alias terms.

Multi-Tone Power Ratio (MTPR) is the amplitude difference
from peak amplitude to peak distortion (either harmonic or
non-harmonic). An 8 tone pattern is loaded into the D/A. The
tone spacing of this pattern (∆f) is created such that tones 1
through 4 and 5 through 8 are spaced equally, with tones 4
and 5 spaced at 2∆f. MTPR is measured as the dynamic
range from peak power to peak distortion in the 2∆f gap.
Intermodulation Distortion (IMD) is the measure of the
sum and difference products produced when a two tone
input is driven into the D/A. The distortion products created
will arise at sum and difference frequencies of the two tones.
IMD can be calculated using the following equation:
