Nobody has suggested that. --- Quote ---You cannot have 40 year old analog scope as your first and only scope as a beginner. --- End quote --- Absolute nonsense. Having taught beginners, they understand them better than to complex modern scopes with subtle and important config setting buried in a menuing system. --- Quote ---My advice... --- End quote --- Is valid from one limited viewpoint. --- End quote --- You and most other analog scopes aficionados seem to take this personally and emotionally. I don't disagree with your decisions for yourself. I couldn't even if I wanted to. They are your decisions about your life. --- End quote --- You know nothing about my background and experience, nor my views on digitising and digital scopes. But that seems not to stop you shouting your preconceptions in a long rant that I've omitted for everybody's sanity. For the record I've been using digitising scopes for >40 years and digital scopes for >30 years. I've also had long discussions with the person who had (and was continuing to) design HP's high-end digitisers. I am perfectly happy to use a decent digitising scope; the modern ones do their job well, even if there are extra subtleties that catch out the unwary. |

Long after any hard drives and/or flash memory in a modern scope you might no longer be able to get firmware for have stopped working, effectively turning it into a door stop. --- End quote --- But modern 'scopes can do more and they fit inside modern apartments. If you grew up with that old gear then I understand that there's a certain fondness for it. Those old 'scopes emit a reassuring smell as they heat up, etc., but a youngster won't have that nostalgia. |

All I see is you recommending how great idea is to push an analog scope at unwary beginners "because it is good for their soul" or whatever.. Length of my rant is not even close to being proportional to how many times i hear this utter nonsense being repeated in this day and age.. And I didn't mean to offend YOU... Being analog scope aficionado is same as being gourmet food aficionado: nothing wrong with that, it actually points to good taste and wast knowledge of the topic. It becomes inappropriate, when such person gives truffles recipes to person that cannot afford food. It is not wrong, it is not from bad intentions, it is just not helpful to a person in question. And as I read many of your posts (most of them being pure gold) i do believe you know very much about every type of scope there is in existence.. In fact, you know so much, that you forget how little beginners know... You know, those people that find single transistor amplifier overvelmighly complicated... I know, I'm sure guilty of that too. So, it's not my intention to aggravate you, or belittle iota of your knowledge.. It's just, fact is, old analog scopes are museum pieces. If you're lucky to have specimens that work well, and you enjoy using them, lucky you. They reached status of oldtimer cars. Sure there are many vintage cars people keep running and eve use as daily drivers. Old vintage car might be a good car for a beginner mechanic. Not for a beginner driver. Good first cheap computer for beginner programer is Raspberry PI, or any cheap moden PC, not vintage IBM PC XT, good first car for beginner driver is few year old small Toyota Yaris bought with at least minimum warranty, and good first scope for an absolute beginner is cheap modern DSO.

[...] --- End quote --- Doesn't it all depend on the beginner? It's like with cars: Some guys are better off buying a new car, if they are more interested in driving than fixing cars. They might be inept at fixing cars, yet be a pretty good driver... and vice versa! Or, consider the relationship between a pianist and a piano tuner... In other words, a good decision could mean either buying a new or a used scope, depending... on you! :D |

--- Quote from: george.b on October 13, 2020, 04:13:49 am ---That's pretty brutal. What's the story there? --- End quote --- LOL >:D yeah, it was bought many years ago from Israeli's seller that sell T&M equipments that looked like they're ran over by tank in war zone. :palm: I was lucky on the timing, that the seller was going to close their shop put everything on big sale, and offered me these gems for a good bargain. |
