AC TESTING—HISTOGRAM
The ac testing histogram tests the ADC for the code distribution
for the ac input, computes the mean and standard deviation, or
transition noise, of the converter, and displays the results. Raw data
is captured and passed to the PC for statistical computations. To
perform a histogram test, select Histogram and click Start Stream.
8-/10-Lead PulSAR User Guide
Note that an ac histogram needs a quality signal source applied
to the input J6/J10 connectors. Figure 23 shows the histogram
for a 1 kHz sine wave applied to the ADC input.
Figure 23 shows the histogram results for the signal applied. It
also illustrates the different measured values for the data captured
(see Number 1 within Figure 23).
