I am thinking to buy a Digital Oscilloscope, but oscilloscopes are insanely expensive.

I would really appreciate if someone would guide me in selecting the an inexpensive but with good value.

I am using it for general stuff.

Hah! Try pricing out a multi-GHz 4 channel Tek scope if you want real sticker shock!

Basically - for a new digital scope - there are few nice options for under $500.00 USD (Rigol and Owen - mainly); dual-channel, 50-100 MHz, somewhat "hackable" (if you're into that), lightweight.

Then you have the slightly cheaper "Pocket DSOs" that float around out there (most for under $200.00 USD).

Finally - there are the USB scopes (BitScope and the like) - some of them are quite nice, and not really super expensive...
I will not respond to Arduino help PM's from random forum users; if you have such a question, start a new topic thread.

What do you mean by "Digital Oscilloscope" ?

Do you mean a 4-8 multi-channel Digital Storage Oscilloscope? Or an oscilloscope with an LCD flat screen?

You can buy used pretty good Tektronix *Analog* scopes on eBay for a pretty good value.

A better option may be a logic analyser, rather than a scope, depending on your application.

I don't know what you are looking for but reasonable scopes these days are insanely cheap, for $400 you can get something that would blow the socks of a scope that would have cost as much as my first house 30 years ago.

Logic analysers cost almost nothing now but they were just a dream, even for a small company.

Compilers are free, they used to be $100s of even $1000s.

Debuggers cost $50, you used to need a second mortgage.

Yeah I know, "when I were a lad", I'm in grumpy old man mode but really, the entry costs for electronics these days is lunch money.

Of course if you want a scope with 1 GHz bandwidth I will agree with you :)

I totally agree!

Our electronics section was cleaning out the old instruments recently, and some of the scrapped cathode ray tube oscilloscopes had cost several months pay when they were bought.
Now the same task was solved on a small handheld instrument at a fraction of the cost.

Hand held calculators were so expensive once, that acquiring them at the department of Physics had to be approved by the Head. And they were registered as scientific instruments upon arrival.


..... and the first handheld GPS receivers we got in the army! The size and weight of a brick, the price of a family car..... but they were pure magic!

You guys are funny - next we'll be hearing about how you had to walk to school, in the dark, uphill both ways, in the snow, carrying your book & a piece of chalk, to a one room school house, where you'd study by candlelight ...

And still no word from OP on what he had looked at.

Guys, I highly appreciate your reply.

I've looked at those on Ebay, but cannot decide which to buy. At the moment, Rigol DS1052E seems to be most tempting to me.

Atten Digital Oscilloscopes 40MHz ADS1042C


ATTEN ADS1022 DIGITAL STORAGE OSCILLOSCOPE 25MHz


SIGLENT SDS1022C 25MHZ Digital Oscilloscope


OWON Digital Oscilloscope PDS5022S 25 MHz


Rigol DS1052E.

I also looked at a DSO201, ?Scope and DSO Quad. I like the look of the dso quad, the dso201 doesn't really get my interest since it seems to be a single channel. There are times i've needed at least 2 channels at the same time. I see people on Amazon calling them "Hobbyist Scopes". I'd like to get a DSO if it has reasonable automotive use.

If are you going to look at clock related signals, the 16 MHz clock or the 8 MHz max speed SPI clock, then go for the highest bandwidth you can.

http://www.rigolna.com/products/digital-oscilloscopes/ds1000e/ds1052e/ 50 MHz  
http://www.rigolna.com/products/digital-oscilloscopes/ds1000e/ds1102e/ 100 MHz

At the same time, a Saleae Logic analyzer for $149 can use clock in those same SPI signals and analyze the data stream for you

and do timing measurements too.
Doesn't do analog tho.

It 1M samples is its lowest setting - it goes up to 10 Billion samples!  So you can catch a lot of stuff going on over a long time span.

How's this look as an alternative to the free-standing scopes?

If you're on an insanely small budget like I was, look on Ebay for Tektronix 22xx series scopes.  Got a 2236 (100MHz) for $100 (with free shipping) and works like a top.
