so i am getting into motherboard repair, mostly in laptops and desktops. ive been looking at everything i need. ive got most of it, but i dont know if i need an oscilloscope or what kind. ive been trying to do my research but im getting a bit confused. i dont know if i even need one or if i just want one, i dont know what bandwidth i actually need, i see things like 20Mhz up to 1-2Ghz. what about the S/s. im sure i dont need anything crazy powerfull, but i dont want to get something that almost is what i need either. any thoughts and suggestions are appreciated. |

Max budget ? |

Generally if you don't know if you need an oscilloscope, you probably don't need one. This actually applies to many pieces of test equipment. |

You can easily find a very nice analog scope for under $75-100 in good working order, used. These days you should be able to do much better than that, even. (Outside of ebay - which adds some overhead - $20 seems fairly common for decent quality dual trace analog scopes from the 80s and early 90s) Dont get anything older than that - The major brands of the 90s in particular, workhorse scopes made for schools and basic working lab scopes are often very good buys. Just don't jump on the first one you see. Try to get one without unobtainium parts - ask here - whose service manual is also online, thats listed as working, not 'for parts or not working', so you wont get somebody else's headache. Watch Dave's segment on getting your own old analog scope. Its all very good advice. |
