ADC1 Instruction Manual Page 25
32K B-H FFT, -3 dBFS, 10 KHz
The above FFT plot shows that the ADC1 is free from jitter-induced sidebands. Any jitter present at
the conversion sampling circuit would produce sidebands equally spaced above and below the 10
kHz test tone. The tone at 20 kHz is due to second harmonic distortion, and measures almost 120
dB below full scale. Note the near absence of spurious tones.
