13. Verify the Clock Source, Sampling Rate, Number of Samples, and Configuration of the
MAX11156 ADC, and click the Set button.
14. Go to the DMM tab, select mV from the Display Units pulldown menu and click the
Capture button. The reading of the MAX11156 ADC should display a small number in
mV. That is the reading of the 0V (AGND) input. Make sure that all inputs are grounded
by shunts on J28 and J29; see the ADC Input Configuration table, Table 1, and the
MAXREFDES74# schematic.
15. Go to the Scope, Histogram, and FFT tabs to verify functionality and performance of the
0V reading. Set the Sampling rate and select the Number of Samples, the Display Units,
and the Average from the corresponding pulldown menu and perform a read operation
by clicking the Capture button. The corresponding print screens are shown in
