Which Best Digital Osciloscope Quality/Price

Hello folks Not sure if this is the right section to post but I'm looking for some opinions about Digital Oscilloscopes.I want to buy one but the market is flooded with different models with different frequencies so I'm not sure what is the best for me. Can someone advise me what points are important in this moment of choose? Sure the bigger price are best but perhaps I don't need a Top Scope

1) What exactly do you need to measure? 2) There is no 2

Well I want to measure some arduino PWM signals and I also do some Tv repairs and monitors. The logic analizer would also be important feature

The main criteria when buying a scope is what is it needed for. What frequency ranges do you need to measure, how many channels do you need, does it need to do analogue & digital (yes), does it need to be a storage scope. Beyond that comes considerations like cost, how heavily does it gets used (pointless buying small cheap scope for continual benchwork) does it need to be portable (maybe battery powered)

What's the min/max frequencies, voltages?

How many channels do you need?

If you only need two channels and 100mhz will do it for you, a very inexpensive scope that is of very good quality is the Rigol DS1102E

A better scope seems to be the Agilent DSO2002A which is about $1300 for 2 channels @70mhz but it has double the sample rate of the Rigol, a much better display, and a lot more features. It can be software(!) expanded to 4 ports, 200mhz per port, and an 8 channel logic analyzer that is synchronized with the analog side. With all the goodies it's about $3000, though.

Thanks for all answers in special to JoeN I was looking for that answer. The scope Rigol DS1102E it seems to handle the job. I also found a comment on EEVblog describing it. I will search for more info about it Any more models and opinions are welcome

Look on ebay and craigslist and such for a good used scope. These are usually a great bargain for a hobbyist.

Stay away from the cheapie pocket scope things, if you have any interest at all in analogue performance. http://www.eevblog.com/2010/05/11/eevblog-86-buy-a-real-analog-oscilloscope-please/

Get the Rigol. It has a good price and good reviews, even from folks who are really interested in high quality analogue performance.

Don’t tell anybody I told you, but… apparently the DS1052E can be changed to a DS1102E via the serial port.

I’ve recently acquired a ATTEN ADS1102CAL+ - which sounds like its related to that Rigol model - has 7 inch screen which
is really nice to have. 100MHz, 2 channel, 1GSPS, etc etc. No complaints so far.

Where did you purchase it and how much it cost? Looking on ebay I found it at a good price I think? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=150620675417&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en

Amazon I believe, 'bout £300 UKP. Seems to be popular and going down in price since I got mine ...

RIGOL OEMs it to a number of companies including ATTEN.

Rigol oem'ng for Atten is like GM oem'ng for Ford.

Don't tell anybody I told you, but... apparently the DS1052E can be changed to a DS1102E via the serial port.

Word on the street is that they tightened up the firmware to disallow that. You have to find an older model with a firmware version older than something or the other otherwise the patch won't work. I would do an Internet search about that before buying the $329 model thinking you can patch it yourself. $399 isn't that much anyway...

They used to make the HP low end scope too until it was replaced with the new and fancy scope I mentioned earlier.

I have a digital scope and a Saleae logic analyzer. I use the logic analyzer 99% of the time. It costs around $149.

The Logic does a lot more, in many respects, than a digital scope (unless you pay, like, $10,000). For example, it captures up to 10 billion samples (via USB upload). It analyzes protocols (I2C, SPI, Manchester, CAN, Serial, etc.). It is quick and easy to use. I reach for the Logic a few times each day. I turn on the scope once a week or less.

My recommendation is get the Logic, and supplement (if you need to) with a cheap digital scope like the Atten, which you can get for under $1000. That's for when you really need to see the analog signals (which isn't that often when working on microcontrollers).

You could consider the Logic 16, which samples up to 100 MHz. ($US 299).

This isn't an ad, honestly. It's just my honest opinion.

I have an ADS1102CAL too, which I purchased directly from HK via ebay (the seller was aonehere). No complaints so far. Just remember that depending on where you live, you may have to pay import duty and/or VAT.

The Logic is nothing but a 8051 development board + a software piece. The really bright spot is the software piece. As such, you can get certain cheapo 8051 boards and flash with the right vid/pid and it will work with their software. $20 max.

The same with the new Logic 16.
