100MS/s PC Based USB Digital Storage Oscilloscope, DSO 2090

NO scope is worth a single penny when the results that it provides are not real!!!I see some people here claiming that this scope is worth it "for the money". Well, you can go spend this amount on an old Tek that will give you better results than this ever could.After repeated failed attempts to compensate the included probes, I switched to some nice Tek and Agilent probes... Still no luck. Funny, one probe with one compensation setting gives different results on channel 1 than channel 2 - What a disappointing, useless brick this DSO is!!! Unbelievable that you could charge $200 and not even ensure that the channels are matched.I will never buy this brand again... I am returning this junk and buying something else.

Just Useful but not a good scope

I have only used this a couple of times so far. It very easy to install and set up. This device cover all the common uses of a scope and then some. If it proves to be durable this will be a gem.

high voltage capability is zilch, can only give 5v/div, tops out at +/-20v. Voltage scale is not listed on the screen. Limits not advertised. Voltage and time increments should be displayable the X & Y axis.

Took me a couple of hours to get familiar with the software, calibrate and check out the DSO to convince myself it gave accurate readings. In short...it works great. Not as nice as the $10,000 DSO I used to use at work (I am a Electronics Engineer), but it is absolutely amazing for less than $200.This DSO can do anything I need to do in my home lab. (I wouldn't recommend it for designing missile guidance systems.) It is limited to 35 VAC RMS input but that is plenty for working with digital systems. I am not sure why some of the reviewers were so negative. Some of their comments are incorrect. It helps if you read the help file located in the software application (the manual that comes with the product is a joke) and have previous experience using scopes.

excelente producto

I bought the 100megasamples/s version. Works ok, easy to setup and use. Of course, the documentation is minimal, but if you're familiar with other 'scopes you can figure this one out.However, don't believe the blurb that says the bandwaidth is 40MHz at 100Ms/s. It ain't so. I cannot get a 32MHz signal to show up. I believe the real b/w is close to 20-25MHz.

It's all what I was expecting to be. I would only complaing about the lack of information in the instructions manual. But it's ok.
