Pete, Which Rigol model do you own?
I very much agree with you. I don't want to plop $400-500 down just to get a scope, then realize I really needed to plop$1000-1500 to get what I needed and now had waste $400-500.

I went a long time with my Rigol without an "unavoidable use case" for logic signals involved with debugging new hardware, but when those use cases finally came around it was nice to have the capability and not be looking around for another piece of equipment, most especially when you need to see what's going on with several signals at once. In about seven years I think I've topped out with two analog and seven or eight digital signals with one set of gadgets. The integration of digital and analog is a real plus, for instance where you need to jump around between figuring out a noise issue vs something basically wrong with a serial line like with I2C. And of course you can correlate analog such as with A/D converters with digital signals feeding them to sort out issues. -Pete _______________________________________________ Triangle, NC Embedded Computing mailing list To post message: [email protected] List info: http://mail.triembed.org/mailman/listinfo/triembed_triembed.org TriEmbed web site: http://TriEmbed.org To unsubscribe, click link and send a blank message: mailto:[email protected]?subject=unsubscribe _______________________________________________ Triangle, NC Embedded Computing mailing list To post message: [email protected] List info: http://mail.triembed.org/mailman/listinfo/triembed_triembed.org TriEmbed web site: http://TriEmbed.org To unsubscribe, click link and send a blank message: mailto:[email protected]?subject=unsubscribe
