Getting non-event based data.

SOD was designed for event based data, but you can use SOD to get continuous data.
What you do is request a set of specific time windows.
It is a little convoluted, but you use the <CSVEventSource> to put in "dummy" events,
either just one, or regularly spaced like once per hour or day. Then, down in
the waveformArm, use a <originOffsetRequest> to generate the time
window relative to these fake events. If they are regularly spaced, then the
request window would be the same, one event per hour then request one hour time
windows.

Here are the links to the docs for these two ingredients:
