Anyone fancy trying to illustrate the configuration settings?

Here are PNG templates:

Did you arbitrarily draw those waveforms? Or are that actual data from one of your triggers? The only reason I ask is I think it would be extremely helpful if we could come up with some physical process for obtaining raw piezo output for analysis. I'd think it woiuld be much easier to deal with touchy feely data than some vague and arbitrary values leveraged against a completely unknown quantity.

What I mean is if we can generate waves to look at it should be extremely helpful overall. We could increase/decrease piezo distance to the head. Check waves. Dampen head. Check waves. Try different foam cones. Check waves. Review waves to help shape how the module should be handling them for processing. And on and on and on.

I'd be extremely interested to know if MD could provide the raw data itself, even if just a small slice of it. Obviously the raw signal is in there somewhere.

Obviously you will understand I have never looked at Dmitris, but I have it on good authority that everyone is different, so yes!

You might like to xoscope - somewhere in this thread.

As far as I know the waveform is sampled in tiny quanta, analyzed then discarded.
Only very important bits are intercepted via satalite by the state dept'.

In the UK Mr Blunket is over the hill - but he's still in danger of being xoscope'd
