I've repaired devices for over 30 years with pretty much anything, just know what is broken and what portion of the scope not to use. if the horizontal trace doesn't work, and you have a Z axis still viable, you can use the pattern of the vertical line depending on what trouble you have. There is no Z axis in DSO these days. Non-linear, uncalibrated? Most any cheap device will hold a calibration for some hours, just calibrate the segment of voltage and frequency you need, find out where the slope changes, and recalibrate at that level. DSO nano or whatever is OK for DC to 30V or maybe 50V, I don't recall, at which point there is a shock hazard with DC, so its really meant for general/hobbyist electronics work. You needn't dream, just study. --- Quote from: BoredAtWork on October 12, 2010, 05:06:35 pm --- --- Quote from: saturation on October 12, 2010, 03:17:43 pm ---Scopes don't give you skills, nor does paying a lot of money for it or hacking it to get more bandwidth, knowledge does, and properly applied, you can do serious work with a toy. --- End quote --- With an uncalibrated, non-linear, unsafe toy?

"knowledge is power". but yeah, if you just want to have a scope to use (not learn/hack or play) for a some serious work that you want to save some of your hairlines, then a serious scope is the way to go, IMHO. ebaying the "toy" just now, the price is around $40. if you think you cannot waste that, then get a $400 "toy" ;) ps: hence knowledge is I squared R :D logical reasoning ??? |

I bought an used analog scope some month ago, and I think it is worth every cent! so, when I play around with some microcontrollers, and the clock doesn't work, I don't keep wondering any more. My old scope does it. apex |

Regardless of toy, used, or brand new DSO, enjoy your adventure into electronics. |

What do you mean? It's run from a SELV power supply which makes it safer than most mains powered 'scopes. It's only unsafe if used incorrectly i.e. to measure hazardous voltages but it clearly states the maximum input peak voltage is 50V. The toy 'scope is probably better than a sound card and will teach the basics. The kit version will also teach MCUs, assuming source code and an a schematic are provided; I haven't checked this and if so I might be tempted but because it'll help me learn MCUs not because I want a 'scope - I've already got a couple of nice old analogue 'scopes which are better than the toy will ever be. |
