Hantek DSO1202B

[rickman]

I found this while looking for USB scopes. It is handheld, but can be
used with a PC too. It has a 1 GHz sample rate so 200 MHz bandwidth
isn't so difficult a claim to believe. I can't find anyone who has used
it though. There is a lot required of the software to make this useable
and useful.

Funny, I don't find it on the Hantek site at all.

Opps, the USB interface is the slow version, so it would only be useful
for control, not so much for using the PC as the user interface. Still,
not a bad device.

I just can't find any reviews.

I realized that the bandwidth/price thing is excess markup. There are a
number of units that can be "hacked" to function at the full bandwidth
of the higher speed models. That means the scope hardware is the same
and the performance is crippled in the slower units via software.

Those little pushbutton scopes are a nuisance to use. Get a Rigol or something
with a big screen and proper knobs.

Is that an order? I don't want a hunk of iron either on my desk or in
my bag. My first choice is a USB only scope with the PC as the UI. I
am thinking the Hantek might be a good compromise, but it isn't really
an umbilical scope.

Agilent does that nowadays. You can buy a cheap scope and later pay them more
money and they will send you the key to unlock more bandwidth.

That shows clearly that there isn't enough competition in the market.
If even the overseas vendors are doing it there needs to be more
competition.

I dont know, but it's cheaper here.

Looks to me like it will tip over when you push those tiny buttons. And the BNCs
are on top, another great way to pull a little on a probe and tip it over.

Geeze, Larkin. I was looking for someone who had experience with this
unit. I can look at pictures and guess what it might or might not do.

If it has a decent front end and the UI isn't bad, I can live with the
probe connections being on the top.

Do you actually *know* anything about this unit?

 

[rickman]

This one? No, it's pretty obscure, and the web site is awful. I have used
nonstandard scopes, ones with funny shapes and pushbuttons instead of rotating
knobs, and I've found them to be awkward.

If you are really impressed by this one, buy it.

Boy, you are really obnoxious today. What is with you? No, I take that
back. I don't want to hear any more crap from you. If you have nothing
to add to the discussion, please just go away.

 

[rickman]

So it's about 25:1 now that you *will* buy it.

I used to think you were mostly badmouthed by many of the others here.
But I see what you really are like. You have some sort of pathological
need to create drama in your life, or at least here.

Don't pretend that you come here for the technical discussions. We know
that is BS.

I think I'm beginning to understand why you have received threats from
others in this group. lol

 

[rickman]

Sorry. I meant 100:1.

You really can't control yourself can you? I just can't imagine there
isn't someone, somewhere writing a thesis on personality disorders as
exhibited on the Internet. If they are, I'm sure they are tuned in here.

Hey, I expressed my technical opinions about that silly combination
scope/dvm/purse. You have been the one going personal here.

It's probably a bad scope and a bad DVM. I only buy Fluke DVMs because
the cheap ones are too easy to blow up. I can imagine all sorts of fun
when the DVM and the scope are the same expensive instrument. I bet
all that scope electronics trashes the battery quick, even in DVM
mode. Heck, are the DVM inputs isolated from the scope inputs?

actually they are, they even have the standard Z inputs.. 1 and 10 megs.

I'd get a Rigol. Well actually I did, but I have a Tek boat anchor too.

Incidentally, I don't like the Rigol software interface, but to be fair,
I haven't tried to update it in a while. It was a pain to get it working
on win 7 64 bit. I was pulling in DLLs and other nonsense to give win 7
the flavor of XP. What I plan on doing is using the XP VM you get with
win 7 pro. One of these days.

I actually never asked your "opinion" based on photos. I asked for
people who *know* something about it. You just can't resist giving your
opinion no matter how baseless it is.

You have correctly evaluated the problem. If everyone would simply
not respond/reply to Larkin's posts, the problem will go away.

More cackling. Say something useful about electronics now and then.

Pot, meet Kettle!

You really do have some sort of emotional issue about all this don't you?

I have a picoscope. Only a flat box with 4 bncs. The sw is good, even has fft. Real handy for travel as it packs easy

Thanks. Picoscope comes highly recommended. I just don't want to pay
$2k for something I'll drag out twice a year or so.

We'll see, I don't have to buy anything right away. It's hard to make a
decision without knowing anything about the UI.
