4.3 NOISE HISTOGRAM WINDOW

The noise histogram window displays the ADC output in histogram form, building the

number of occurrences in each bin with each consecutive sample. The difference

between each bin from the mean in units of LSB is given as the y-axis. The sample size

can be changed in the configuration window.

4.4 AUXILIARY DATA WINDOW

The auxiliary data window shows calculated data based on the current sample size.

The mean of the sample set is given in both LSB and PPM. The standard deviation or

RMS output noise is given in units PPM. The overflow bits of the MCP3551 are also

monitored and the overflow bits are also given for both overflow high and overflow low

situations.
