Tablet Oscilloscope-tbook, a new kind DSO.

[alm]

They should really offer an active probe (and a dedicated 50 Ohm input) for the GHz bandwidth scopes.

Good point. The 1 Mohm // 15 pF input impedance wouldn't even work with the Agilent/Tek/Lecroy 500 MHz Hi-Z passive probes (the only ones I'd trust to kind of meet that 500 MHz spec), since most only compensate up to 12 pF or so. It looks like the included probes are 250 MHz. How are you supposed to acquire a 1 GHz signal? I think Tek makes a 1 GHz high-Z passive probe, but I doubt it uses a standard BNC input and four of them may cost more than this scope. In general you'd use active or resistive divider probes at these kind of speeds, so at least provide a 50 ohm input option so people can use / hack third-party active probes. A 50 ohm feed-through terminator isn't going to perform well at 1 GHz either, I think the Pomona one is only specified up to 500 MHz or so (even without a capacitive scope input on the other end).

Right, I know because I have one. [POMONA ELECT 4119-50, TERM 50ohm 2W]

I haven't been able to find any prices for this new scope but here are some prices I found for some of their handheld, ScopeMeter-like products:

I see, is the price for the Genuine Micsig.

There is another possibility for a control interface in addition to the touch screen. A little box with two or three knobs and a few buttons that connects to the main scope with bluetooth. Then you can put the control right where you are working and control important things where you are and not need to awkward actions on a touch screen.  It doesn't need to have too much, maybe two knobs, two or three buttons.

According to the specs these scopes have no 50 Ohm inputs. This makes them useless for frequencies over 100MHz. A high impedance passive probe loads signals over 100MHz too much and low impedance passive divider / active HF probes need a 50 Ohm input.

Either someone has slipped a decimal point on those prices or they are on the wrong planet.

LOL ... Is true, but are Genuine Micsig.

Just change supplier. At the other end of the scale:

Looking at taobao, the Micsig handheld scopes vary in price from 9676 RMB ($1591) for a MS310IT to 32880 RMB ($5406) for a MS610R.

Three things I have found difficulty in with using touchscreens (Ipad) :

As said , they are difficult to use if your hands are larger .
Often your hand obscures your view when placed over the target area .
Any material on the hands is smeared over the screen , not good in a workshop environment (although a filthy front panel is not so good it doesn't generally affect use on normal physical interface DSO) .

I love BNC connectors, but isn‘t there the small risk of electrocution when BNC’s are used on a probable device that doesn’t have proper ground/earth? 
Some Scope Probes have exposed metal connectors, so if the Unit Under Test (UUT) has a ground/earth fault then the engineer could risk electrocution, if the connector is touched while still connected to the UUT.

That's why my Fluke Scopemeter has automatically retracting plastic shrouds that cover the barrel of the BNC connectors.  The UUT ground potential in not exposed anywhere on this scope.
The probes are also fully insulated.

Knobs and buttons are really needed.

As for knobs, well, I don't know of any hand held scope on the market that has knobs?

Men like to play with knobs. 

Sorry... couldn't resist.

[Stonent]

I suppose someone could just make a backpack for an android or apple tablet that has all the dsp and fpga goodness.

When I first saw this I thought, OK mount a Hantek scope in a box and mount it to a Microsoft Surface tablet.

The surface is most likely glass so wiping it clean is a piece of cake. Another advantage is that buttons won't stick, no dirt gets into switches, etc.

I do wonder where they get their 1GHz front end from, and 300K/wfmssec, I'm mean, that sort of bandwidth and speed doesn't just pop out of nowhere from scratch from a new company.

The Chinese are excellent reverse-engineers...

Given the fact that so many companies prefer to outsource their production to China and thereabouts, just to make a cent more profit, it stands to question that they really need to do that much reverse engineering at all. Right now "we" are more than happy to hand over our designs to them, just so they can manufacture it cheaply for us.

Even then it really depends on the person and how you use it. I'm exactly the opposite - I hate using a mouse with a laptop. Really, I hate using a mouse period. Crappy interface, whose dumb idea was it to communicate with the computer using a dead rodent tied to a port? I love that the pad is right underneath the keyboard. I can switch back and forth between them without even moving my arm.

Whose idea?

... and video conferencing on a computer, while collaborating on the same document, and a boatload of other stuff that we just now consider "advanced".

Might be interesting to see if their isolation prevents a 300v spiky signal on the probe ground messing up the (presumably capacitive) touchsreen.

Just wondering about the ratio  of capacitance across the isolation barrier to touch capacitance - I'd be impressed if it didn't cause at least some jitter.
   

[Micsig]

I don't see it going over well. People want knobs. Also you gave no specs.

Does it have wifi? Does it have a full OS like Windows 7/8, mini OS like RT or CE, Linux, custom?

WIFI is optional.  only Android system, no OS above your mentioned. Android is optional too. 

[Micsig]

As well as the "1GMHz" it boasts "up to" 5GSa/s, 200,000wfms/s and 360Mpts memory depth. Oh, and an integrated 6 1/2 digit multimeter and a waveform generator.

All of these world-class specifications are repeated three times on the page, so they must be true...

[Micsig]

Very original.

our name is from Micro and Signal, is there any problem? do your mean the font  is simliar?

[Micsig]

hello, here i would like to introduce a new kind DSO to you. Tablet Oscilloscope-tbook series.

You found EEVBlog - good first step.

Now - if you want to sell some of these the next step is to send one to Dave for a proper review..

it is highly appreciated your suggestion.

[Micsig]

BTW, Micsig are not spamming the forum, they have permission to post here.
The form factor aside, the specs seem very impressive for a new company.
I do wonder where they get their 1GHz front end from, and 300K/wfmssec, I'm mean, that sort of bandwidth and speed doesn't just pop out of nowhere from scratch from a new company.

I'll withold further judgement until you or Mike takes one apart and shows us what's inside.

But Micsig, show us a video of the device working. Hopefully not a professionally done marketing video.

Nice specs for both the tablet and handheld scopes, can you provide a link to the manuals of both?

P.S. forgot to ask: are the scopes already available? Where to find those scopes ( in europe preferably )?

Manuals will be uploaded to our web later, pls continue to foucs on us.

Our partners will put the advisement, pls wait.

[Micsig]

why dont they send to someone like dave to have it reviewed? it would be a good DSO if it meet its specs. well it could hit the market if it could compete to other manufacturers.. how about the price range? if it cost much cheaper than leading manufacturers it would be attractive to entry level like me...how i wish to have one on my bench....

thanks for your advice. i will provide you a big discount.
