"I can think of one drawback for each option, therefore I can't possibly choose!" Look, I get it, I feel that way too sometimes, just remember that you have intentionally excluded the common mode from your analysis. It is irrelevant for choosing between options, but the fact is that all of our choices are good and cheap these days vs not too long ago, and that fact is hiding in the common mode. If you can't choose right, you can't choose wrong. Roll a dice if you must. |

It seems you have to forcefully give up on something, while implementing such stuff would be quite easy for the manufacturers. --- End quote --- Claiming that means there is no viable scope is ridiculous, though. Engineers and hobbyists have been using various scopes for decades. All the way back to tube-based analog scopes. And now suddenly none of those scopes are good enough for hobby use? Sure, features are nice to have, but none of them are essential. --- Quote from: coppice on October 24, 2022, 05:38:57 pm ---Lots of things might happen to oscilloscopes in the next 10 years. However, nothing much has happened to DMMs in the last 30 years, except who makes the popular ones. Why would that change in the next 10 years? --- End quote --- The HP 34401A had a alphanumeric VFD, while the 3445x/6x/7x series have a graphical LCD that can do trend plots, histograms etc. On the handheld front we have some models like the Fluke 289 that have similar features. I'd say that's progress and something that can be very useful if the form factor allows a large enough display (e.g. bench DMM). I wouldn't expect too much change on the analog side, we're not going to see 6.5 digit handhelds becoming popular. But I expect changes in the UI, just like the Keysight 34461A is quite different from the HP/Agilent 34401A. Also I expect to see the digital sampling of AC signals (what Keysight calls TrueVolt) instead of analog True-RMS converters to become more common. |

The future of digital multimeters will be wristwatch multi-meters! Duh! :-DD |

--- Quote from: balnazzar on October 24, 2022, 05:38:22 pm ---Exactly... They could make it silent at little or no cost at all. |O And, as I said elsewhere, the pc workstation I built is much more silent than a commercial A-brand workstation (that costs 2X at the very least) with the same specs. That's because I implemented good airflow, sensors, and bought quality fans. --- End quote --- It actually isn't cheap or easy to make things reliable and quiet. If customers demanded silent products the market would necessitate their production. I'm guessing you are just bothered more about fan noise than most. I've built quiet PCs too--with a great deal of effort--for special purposes (HTPC/Hi-Fi room) but other than that unless it is a very whiny rack server fan, I'm not really bothered by a bit of fan noise. The only instrument I have with a truly annoying fan is an HP signal generator that sounds like a bench grinder. And as for cheapo vs A-brand, I have two Tek scopes--both over $5K new--that are noisier than either of my stock Siglents. And my Tek PS280 PSU has the loudest fan of anything on or near my bench (the HP sig gen is banished to the garage unless needed). |
