Wow! $123 Hanmatek DOS1102 initial comments
(1/4) > >>
rhb:
Amazon was offering these recently for $123 discounted from $169.  I didn't need it, but bought one because it was cheap.  I'm stunned!! Most sellers ask well over $200 which is too much relative to the competition.  But at $160-170 it's a no brainer for a first scope.  I was able to use it without reference to the manual except for how to save a screen dump.

This is an very good basic 100 MHz DSO.  Risetime is 2.8 ns which corresponds to 125 MHz, but it's at the cost of 16% overshoot.  In other words, the filter slope is too steep.  An external 100 MHz LPF would provide Tek quality overshoot.

Notably it runs on 5 V and there is a lot of room inside for a LiPo pack, so I plan to hack it for battery power. 

I had the display in dot mode when I saved the screen shot and persistence was off. Source is one of Leo's 40 ps pulsers.

Edit:  Added additional screen shots of various things.  Very impressed with the FFT.

Have Fun!

The more interesting option is the DOS1104 for $170.

But the real question is what is the support for these?  You really haven't put it through the mill here.  Are there bugs?  Will they ever get fixed?  Where are the service centers?  What are the triggering options like?  Will it decode serial streams?  What options can I add on later?

These are in that middle ground where your spending enough money to need answers to those questions.  If someone buys a $35 scope and it's a POS, then no big deal.  But a $132 or $170?  That's 1/3 the way to getting a real scope that does come with support and serviceability.

Good examples of this middle ground are the FNIRSI "100MHz" scopes and the Hantek nightmares.  Then there is Uni-T.  They build much better stuff than FNIRSI or Hantek, but have -20% support .. even though they charge near premium prices.

I'm a full believer that having some scope is better than having no scope, but over $100 I begin to worry about how well my money has been spent.

Hanmatek  DOS1102 and DOS1104 are Owon SDS1102 and SDS1104 rebrand.

Their weak point is probably the memory. 10K for the DOS1102  and 20K for the DOS1104.

Is this scope better than the Hantek DSO2C10 in any specific aspect (features / performance)?
rhb:
I have a Hantek handheld junk scope replaced by an Owon HDS272S which is a proper scope with limited controls.  By which I mean I can service a radio with it.

I just returned  a Tooltop ET120M.  I was expecting to return this also, but it is too good.  So unless I discover a show stopper I'm keeping it.

Trade dress looks like Owon's. It's not as feature rich as more expensive scopes, but it has what I use most and it  does the job.  I plan to add as many 18650s as will fit and make it fully portable.  The 10k depth is the only complaint.  I've got a12 bit Owon with 10 million but crappy UI.  I'll have to compare the two side by side.

The Fnirsis are  30 MHz scopes for the same money as the DOS1102.  I know nothing about the Hantek you mention.

Have Fun!
