    Oscilloscope Readout

    • Updated C++ program for decoding (includes sample waveforms)

    We have a LeCroy Waverunner LT584 scope. It is supported by various software (unfortunately all for Windows).

    and allows interactions with a picture of the front panel. With the scope set up to record a large number of segments, it isn't a bad way to transfer data, but requires a human to push buttons. transfer from any Microsoft programming language.

    Visual Basic

    Installed Visual Basic 2005 Express (free). Can easily use ActiveDSO to control and readout scope.

    See sample VB program which reads 4 channels of native (binary) waveform (all segments) and writes to a binary file. This takes ~ 2.5 seconds over ethernet. Of course, one would need to write an analysis program to make sense of the data. Reading and storing ascii data in a text file is much slower.

    callable from (i.e.) visual basic.
