Read oscilloscope data


This web page reads data from the 'input data' field.
Features:
- Analysis of a ramp measurement of a DAC
- Convert sine data into integer values for FFT tool.

Filter the output using index of 'DNL, INL start' taking 'DNL, INL length' values for averaging and using a 'DNL, INL step' for the next value.

Integer range for output data (8-bit:256; 16-bit 65536; 20-bit: 1048576):

For the example oscilloscope data select DNL,INL start: 10; DNL, INL averaging length: 40; DNL,INL step 250; Number of values 16; Ramp INL, DNL.
The first chart shows all data and the selected data set for processing.
You can also use Excel to do the filtering of valid data.
