Typical Dual Tone Dynamic Performance
Figure 6-16. Dual Tone Reconstructed Signal Spectrum at Fs = 1.2 Gsps, Fin1 = 995 MHz,
Fin2 = 1005 MHz (7 dBFS), IMD3 = 64 dBFS
Note:
The output data is not decimated. The spectrum is displayed from DC to 600 MHz.
Figure 6-17. Dual Tone Reconstructed Signal Spectrum at Fs = 1.4 Gsps, Fin1 = 745 MHz,
Fin2 = 755 MHz (7 dBFS), IMD3 = 65 dBFS
Note:
The ADC input signal is sampled at 1.4 Gsps but the data acquisition is 8 times decimated. Thus, the spec-
trum is displayed from DC to Fs/2 divided by the decimation factor
[(Fs/2)/8 = 87.5 MHz].
