| Why do you think there aren't more "good" USB oscilloscopes? |

There has been one point in my life where i reached for my keys when I had to measure voltage, then I realized I don't have a DMM on the keychain. Smartphone keychain dmm does exist but I don't own it. Like if you come across a battery, it would be very useful. The old question of "do I replace batteries or is it broken?" It's because I use a keychain flash light quite frequently (beats the smart phone flashlight), and keychain scissors. If you are fond of battery devices for things like sparsey used lights (i.e. random cabinet light), thermometers, etc, it is desirable. Some of the things I improved with cheap AA battery devices were like a gigantic time saver, and I don't need to wonder how permanent the solution is, I just stick a light in there and if you wanna get rid of it in 3 months, no problem. Cable run requires like strategic planning. Thinking about putting up a easy 10-year life alkaline light system in a shed using 2x 6v lantern batteries. set&forget.Or some bull shit like crawl space lighting, infrequent service lights behind a control panel, etc. Sometimes there is room and you have to work there long and frequently enough to make a built in light worth the effort instead of wearing a head lamp. |

Does a $500 USB audio interface replace a million dollar recording facility? Absolutely not. Is it the best tool for the job when you're fucked for time and need to edit drums on a plane between sessions? 100%. --- End quote --- I have a top of the range National Instruments USB scope, yet I would greatly pefere to use a bottom of the range Rigol/Siglent on the bench because of the convenience. And there is somethign about having a scope right next to your work on the bench so you don't have the glance up at monitor. Same argument for handheld vs bench multimeter for bench use, handheld wins almost every time, you can bring the meter right physically close to the work. --- End quote --- Again- I'm not talking about REPLACING a bench scope. In my experience so far every DSO/USB scope can fuck right off for proper audio work anyway, CRO is the only way to fly when you need latency free probing. This is simply for taking out to jobs so I have everything I need to generate and observe basic signals in a laptop case. More detailed work can always be done back at work or I can return with parts/bench scope/power supplies etc if it must be done there as usually that's beyond the initial callout anyway so it doesn't make sense to have all that with me for a mystery job. Agreed on the bench/handheld meter thing though, my bench meters are pretty much just permanently wired into things like dummy loads and everything gets done with my Fluke. |
