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
