| Best Oscilloscope under $300? |

| Atlan:
Purely theoretically, a 2-channel oscilloscope on channel three, because it is a trigger input. :D |

Like what percentage of times do you really use more than 2 channels? Half the time I'm too lazy to setup 3+ probes on the scope, I just move the probe if I need to see another signal. And with digital scopes you can store the traces if you need to compare things. And with all the triggering options available you can get the similar result. Like sure 4ch is nice, and everyone should probably get a 4ch scope as it doesn't cost too much to get the extra 2ch. But if budget doesn't permit, 2ch will be absolutely fine. I dunno, maybe because I started on a 2ch scope, I learned to work around the limitation, but I certainly would be fine with a 2ch scope, if that meant I can also buy a decent multimiter or another piece of important equipment needed to start my hobby lab. --- End quote --- Just so. Learn to use your skill and imagination - something that's important in any engineering job. (An engineer is someone that can do something for $1 that any fool can do for $5) Besides, decent probes aren't cheap. Probes frequently needed by amateurs cost several hundred $/£/etc. Some professional probes cost several month's salary :) |

Provided they are working, --- End quote --- Maybe in England, but here you can't get anything in working order for less than ~100.- If you buy it online, you have no idea what you're getting. I really don't think a beginner should start with such an old piece of equipment. Does a beginner even recognize the faults? For me, it's also out of question because they are too big and too heavy. You need space on the desk and a healthy back for these. No thanks! ;) |

Modern day oscilloscopes have become super versatile and for somebody at the beginning of their career, it makes sense to start with today's technology as much as financially possible. The other day I read an article about 2 interns (studying fine woodworking) who where working on restoring old ships. Great fun but none of the crafts/wood joining methods used to build old ships is used today. |

Analog circuitry is like "the ghost at the feast" & still comes back to haunt us. |
