But when an internal memory (M1M4) is selected, neither the “Data Format”, nor “Auto-Store” menus shown here will appear. And when the “DO STORE” menu button is pressed, the waveform will

But this will create an output file requiring 1020 times the disk space of the original LeCroy binary file. A one-megabyte reco
