Input power is referenced to full scale. Therefore, all measurements were taken with a 2 dB signal below full scale, unless otherwise noted.
See the AN-835 Application Note, Understanding High Speed ADC Testing and Evaluation, for a complete set of definitions.
Spurious-free dynamic range excluding the second or third harmonic is limited by the FFT size, <−120 dBFS.
Noise figure with respect to 50 Ω. AD9267 internal impedance is 1000 Ω differential. See the AN-835 for a definition.
