PC based oscilloscope? or a DSO NANO scope? for US$ 160 or less?
I am going to buy an oscilloscope, and I need advice.

I have US$ 160 to spend on the oscilloscope.

what you recomend? a PC based oscilloscope?

or a DSO NANO scope?

or something else?

here are some links of possible candidates

Nice toy. 200 kHz only, yes. But it comes in a nice plush flannel sack!
Only one probe, plus a patch cord. Good for audio frequencies, automobile diagnostics maybe.

Input voltage range [-50V,+50V](With probe 10x)Does this mean that you get 10x that range with a 10x probe? Or that with a 10x probe you are limited to those input voltages? not so good.
But this is probably the best one of the listed choices. But it's ugly. There are other things in the tech specs that put me off.

Hantek is a reputable company and their bottom-end USB DSO is not a bad deal, I think. I believe its specs are a little better than the MDSO one.

However... you can get a much better all-around _analog_ scope and still stay within the budget, I think. You can get two of the same probes that come with the Hantek for around 25 dollars the pair, and then you can get, for example, a Tektronix 2225:

Which is a quality instrument, and still have enough left over to buy a pizza.

I have a DSO nano and it is a nice toy. But it really *is* nothing more but a toy. You can use it to see if somewhere is a low frequency signal present. It displays signals with a lot of lag, measuring and triggering functions are poor and it has only one channel, which does not get you very far.
I bought it to have a handy tool to check signals in the field, where no external power supply is available and it has been kind of helpful there. You can use it as a signal detector in your lab or as a third channel if the two channels of your real oscilloscope are busy.

Try to get a low end scope from Hantek or Rigol, they are at least usable for easy tasks on the bench. Technically, a PC scope is OK, but a complete unit is more intuitive to handle, I think.

An interesting question from Tishatang at energetic thread

Dscope
I like the idea that this scope is somewhat homegrown from Germany. Has full support with a forum. Also comes in kit form for less money. Maybe about $100 with probes assembled? Price is in Euros at 59 plus 7 shipping plus probes.

DPScope - A Low-Cost PC-Based Oscilloscope

I am in same situation and the orig poster of this thread. I don't know anything about scopes, and have little money. I heard the Hantek 6022 software sucks compared to their more expensive models? I would assume this dscope comes with better software?

Perhaps someone here could give an opinion on this scope compared to the others in the $100 range.

Many thanks,
Chris

It all depends on what you want / need.

The cheapest serviceable scope going is the USB Hantek 6022.  That is a two channel 20MHz bandwidth affair that can be found for around $75.  Beware of knock-offs.  It has far more features, better bandwidth, and comes assembled for less than the DP Scope.  If you need more bandwidth for another $90. or so they offer the 50MHz 6052.

If you need four channels the price jumps or you will have to go to used scopes.
