TERMINOLOGY
SINGLE TONE FFT
Signal-to-Noise Ratio (SNR)
The ratio of the rms signal amplitude to the rms value of the
sum of all other spectral components, excluding the first five
harmonics and dc. It is reported in dBc.
Signal-to-Noise Ratio Full Scale (SNRFS)
The ratio of the rms signal amplitude related to full scale (0 dB)
to the rms value of the sum of all other spectral components,
excluding the first five harmonics and dc. It is reported in dBFS.
User Defined Signal-to-Noise Ratio (UDSNR)
The ratio of the rms signal amplitude to the rms value of the
sum of all other spectral components within a specified band
set by the user, excluding harmonics and dc. It is reported in dB.
Noise Figure (NF)
The noise figure is the ratio of the noise power at the output of
a device to the noise power at the input to the device, where the
input noise temperature is equal to the reference temperature
(273 K). The noise figure is expressed in dB. 1
Signal-to-Noise-and-Distortion (SINAD)
The ratio of the rms signal amplitude to the rms value of the
sum of all other spectral components, including harmonics but
excluding dc. It is reported in dB.
Harmonic Distortion, Image
The ratio of the rms signal amplitude to the rms value of the
nonharmonic component generated from the clocking phase
difference of two ADCs, reported in dBc. Note: This measurement
result is valid only when analyzing demultiplexed ADCs.
Harmonic Distortion, Second (2nd)–Sixth (6th)
The ratio of the rms signal amplitude to the rms value of the
fundamental related harmonic component, reported in dBc.
Worst Other Spur (WoSpur)
The ratio of the rms signal amplitude to the rms value of the
worst spurious component (excluding all harmonically related
components) reported in dBc.
Total Harmonic Distortion (THD)
The rms value of the sum of all spectral harmonics specified by
the user. It is reported in dBc.
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. It is reported in dBc.
Noise Floor
The rms value of the sum of all other spectral components,
For Noise Figure for an ADC, the equation is
? ? ? SNRFS ? 10 × log ?
Noise Figure = 10 × log ? ?
? V 2 rms /Z in ? ? Encode Frequency ? ? k × T × B ?
excluding the fundamental, its harmonics, and dc referenced to
full-scale and reported in dBFS.

? ? 10 × log ? ?

k= Boltzman’s Constant = 1.38 x 10 -23
T = Temperature in Kelvin = 273 K
B = Bandwidth = 1 Hz
Encode Frequency = ADC Clock Rate
V rms = RMS Fullscale Input Voltage
Z IN = Input Impedance
SNRFS= FullScale ADC SNR
