Low distortion better than 115 dB is required to allow true evaluation of the part One possibility is to filter the input signal from the ac source There is no suggested band pass filter but consideration should be taken in the choice Furthermore if using a low frequency band pass filter when the full scale input range is more than a few V p p itis recommended to use the on board amplifiers to amplify the signal thus preventing the filter from distorting the input signal Figure 18 displays the results of the captured data Label 1 in Figure 18 shows the input signal information The portions of Figure 18 labeled 2 display the fundamental frequency and amplitude in addition to the 2 to 5 harmonics See label 3 also which displays the performance data SNR dynamic range THD SINAD and noise performance Rev A Page 17 of 20 ml Laa cc IE mo Lm PL oam i ADT Ah i i Faare File Help AD 367 IP000000 Amplitude i mrt f il Figure 19 Summary Tab SUMMARY TAB Figure 19 shows the summary tab This tab captures display information and provides this data in one panel with a synopsis of the information including key performance parameters such as SNR and THD Rev A Page 18 of 20 ADC Evaluation Software CIE gw J 3700 L5 ah 7939 06704 019 UG 408 SAVE FILE LOAD FILE The software can save the current captured data for later User is prompted with a load dialog box
