Is there a way to trigger on an out liar in the data being displayed, either through standard deviation or variance, Instead of just a simple value on the screen?

is there an sound alarm or "event fire" for trigger met?

Sam,

There are a lot of advanced trigger functions.  Way too much to go into here.  We have a training movie on that one on our PicoScope CD which is included with every kit or support subscription.

The alarm on trigger depends on what software you are using.  Don't think 6 has this but 5 does.  Not needed though, since each triggered capture is saved in the buffer index.  But...

The PicoScope engineers at Pico listen to new feature requests though.  Many of the features it has now are a direct result of input from the Autonerdz Picogroup.
