Internal Jitter Database (.jdx)
Internal Format Jitter Database Files
Save the jitter database to internal format XML file (.jdx) for backup or when you want to reimport the data back into FlexDCA's Jitter Data Memory. Internal format files are comprised of an ASCII XML with binary jitter data. Both NRZ and PAM4 signals can be saved to internal format files. When you save an internal format file, always save an associated instrument setup so that the jitter data can be properly interpreted by FlexDCA upon import.
Because internal format files contain binary information, it is not useful to attempt to display the file contents in a word processing or spreadsheet program. However, you can convert an internal format file to a comma separated value file (.csv) for use in a spreadsheet or word processing program, by loading the file into Jitter memory and then re-saving the waveform in the CSV format.
