Is there a new way to look at waveforms?

[pwotoole]

Hello guys:
In the old days we used oscilloscopes to check out voltage waveforms. Is there a newer/better way to do that? Something a little more portable? Something that can be handheld? I've used HP(Hewlett-Packert) calculators that will display math curves, such as regression curves or statistical curves as long as the x/y values were added. Is it possible to use a hand-held calculator type device to display waveforms? Maybe a calculator can be modified to do so, or maybe there's one that already does?

Thanks
Patrick

buy a hand-held oscilloscope. or a PC one. calculators are made to calculate, not monitor voltages...

Tons of portable digital scopes are made.......... a little pricy and I'm happy with my analog tek scope.......

Oh gawd, I shudder at the thought of a calculator displaying waveforms.. NO thanks. I like big fat non-protable O-scopes with large colorful displays and lots of bells & whistles.

I doubt there's an easy way to do that on a graphing calc, but maybe someone makes an interface for a PDA. Those scopemeters on the site Lefty mentioned are very cool too, but like he said, pricey.

little pricey Like wow, man. $1400 to $3300.eek: again) I think I'll pass on that.

There are multimeters that have an extremely crude scope function, but they are crap and top out at about 40KHz.
