How often you use oscilloscope?
« on: January 21, 2015, 04:50:38 AM »

I'm planning to buy a used oscilloscope under $200 soon.
I'm debating whether to have a handheld scope or not-too-old benchtop one.
I think I will use scope mostly to test or troubleshoot motor drivers or components that are related to 3D Printer.

Thanks in advance.

got the ds1000E
it is a decent scope for beginners. I use it a lot when i debug stuff

Handheld -> expensive or crap

Ok, here is the deal.
Fact: An oscilloscope is the most important instrument after the multimeter
Fact: A rarely finish successfully a new design without using the oscilloscope extensively
Fact: PC oscilloscopes are crap
Fact: Chances are that your first oscilloscope will suffer from your trials and errors

What you wanna buy is a used benchtop Rigol (or better a new one) like the one cheerio spoke about. 50MHz is ok for beginner. Choose 4 channels. It is a good start since you are not into consumer electronics design and you do not have like 10.000 to spend.

Up until today, my 200MHz 4ch humble wellec served me well in both my designs and during cnc troubleshooting. But now that I design circuits for consumer products i can definitely tell that i have to spend at least 3000 for a descent 100MHz oscilloscope.

if you got a low firmware ds1000E you can flash a 100MHz firmware. I did it and it worked like a charm (it was software trimmed to 50MHz. Hardware is the same)

I couldn't find a 50Mhz used Rigol for two months. And I ended up buying a used Tektronix TDS310 lately for $170.

The seller didn't include probes. I'll have to buy aftermarket or used probes that matches with this scope.

you will enjoy this tool. If you ever work on a cheap crappy scope (like the pc scopes) then you will see the inner beauty of the tek!
