Subject: Re: oscilloscope for CNC

Thanks to all who provided so much info and tips on and off list.
Did'nt expect to get so much material to digest.

For now, I think I'll just use the PC-based oscilloscope, and put off
getting a professional oscilloscope till I get more professional.

Thanks again.

Tanya

your max frequency you want to measure. Digital signals you need
about 2 times unless you want to do glitch capture. Something that
can do a waveform capture is always good. Personally I prefer
HP/Agilent, but I have a Tektronix scope DSP360 ($4000) . The FLUKE
Scopemeter series is not to bad if you want portable and rugged. Stay
away from anything less than 50 Mhz. Look on Ebay, there is normally
a lot of units available.
