It’s the 3rd of 4th video where i can see those white led matrices on the pink foam. An ongoing project?

Az says:

Conclusion @ 53:20
Note: The rambling part is also interesting.

Coolkeys2009 says:

Seems like a very positive and fair review, I’m sure the engineers and others at the factory will be happy, they should shift a few more units.

djmips says:

PCB is reminiscent of the clean look of Sony designs.

Tinker Time Electronics says:

Interesting product, one of the most difficult things I find about dealing with aliexpress is there seems to be lost in translation, sometimes I order things not knowing exactly what I am going to get. Not the biggest deal on lower value items, but on higher value items it’s a much bigger deal.

edocronian says:

All numbers are capital.

fbonacic says:

You have the best tech reviews on YouTube!

Michael Beeny says:

My brain is bleeding!

DigitalAura says:

Does this mean you’d consider selling the Owon handheld scope? Only asking as even that is way better than I currently have access to.

TheAmmoniacal says:

Too bad you didn’t go with the MS220T model! I want a review of that (You can get a cheap version here which is only lacking the DMM option: http://www.ebay.com/itm/322350729928 — $239, but he will accept an offer of $200)

Paul Martin says:

As to the time base, there is a little slider at the very top center of the display, that seems to denote the scroll position. If you tap into that area, are there further controls? It seems like that might be a reasonable place to put fine time-base controls. Just a thought.
Love your videos, thanks for making them.

WHAT A WORLD WE LIVE IN, stereo speakers on an oscilloscope

Negative edge trigger: $7. Are you kidding me?

You know, if you’re doing lab electronic work, _you probably have some money around._ Which is why i can say with some degree of confidence that there may be manufacturers completely eschewing trhe screen altogether on units and instead expect users to have a tablet with a type-C connector to relay information.

Manufacturers would, of course need to accommodate both tablet and handheld form factors for people with high-end smartphones, but the basic premise would be the same, and the software would most likely be easier to use on a larger display. For somebody doing this kind of stuff professionally, a tablet would be a major asset to someone doing field work, since these add-on scopes for USB type-C I am theorizing would have a removable battery (probably borrowing from a laptop manufacturer with commonly-used battery forms), and for tablet users they would need to affix their tablet’s display, which would both keep the phone charged, and power the scope. Throw in a means to charge the scope via aux power and someone on-the-go can charge between jobs very easily, keeping the scope battery topped and plugging it in only when absolutely necessary in a semi-permanent scenario.

Combine with that tablet phone-based functionality and the tablet’s bluetooth can allow for those in the field to take and make calls as they do their work, making the tablet function as a multi-purpose device with some extra specialized equipment attached to it, rather than this bullocks where users are stuck with a manufacturer’s screen and interface decisions. If people need a bigger display, smartphone apps _by nature_ autoscale so plugging it in via HDMI should provide an enhanced experience, and when paired with stuff like the Neonode Airbar, would allow for any display to be touchable.

About things like aftermarket touchscreen enhancements for external displays, it would require a small PC like the RPI2 or RPI3 with software for the touch display unit and system to run it on, so the connected display can interpret touches on the otherwise non-touchable screen as input, and while having something so modular requires a lot of re-learning things, it would overall allow for easy replacement of components and enhanced mobility, so long one wishes to haul with them a display if they want something larger than their phone or tablet’s display and go through the bother of setting such things up in the field.

BlueFoxTV says:

Puts a heat sink on the chip, but no air holes in the RF shield.

Harold Finch says:

These tablets scopes are dumb ass ideas.

Kathy Quinlan says:

I feel like it is Christmas with all the posts from Mike, He may not post as often as some YouTube creators BUT he certainly does have great well commented videos when they come out 🙂 Keep up the Great work Mike 🙂

Mike Hawkins says:

I think the bumper surround makes it look cheap. In all other respects, I think it’s a great product and I’d be happy to have one.

DAVID GREGORY KERR says:

it might not do the 65536 bins FFT.

tim turner says:

I like the mouse option. I have arthritis and dragging around on a touchscreen all day really does my fingers in. The mouse puts that strain on the wrist which is s lot bigger and can handle the motion better

f7497 says:

The only battery powered traditional scope I’ve ever seen/used is a decade+ old Tektronix TDS3014B that belongs to my high school electronics instructor.

RedFathom says:

I don’t think there’s any left handed people in China.

fbonacic says:

are input grounds isolated?

NoName says:

Great vid as always Mike.
Doing better than the beeb with the xmas specials already.

Alfred Stampe says:

Excellent review, thanks. I thought these tablet-like touch scopes were going to be a lot more expensive, but they seem very competitively priced even compared to many of the cheap bench scopes.

navusx says:

With the tilting angle issue. I’ve used the “cricket laptop stand” or similar it works really well with this unit, sturdy yet leaves all the ports open freely accessible.

StarTrek123456 says:

Why are there no touchscreens on “normal” oscilloscopes?

KingofKatenfutter says:

Why the 1k resistor to ground? If you connect the scope earth to live the 1k resisor will just smoke up and go open circuit, leaving the scope at live potential.

Graham Langley says:

Those zero-ohm links at 18:10 are marked ‘LB’ on the ident, so they replace ferrite bead inductors they decided they didn’t need.

Alex Sorin says:

Thanks for showing the screwdriver trick.
Had to open up a similar PSU case this morning and it worked surprisingly well.

victornpb says:

I cannot import desktop scopes to brazil, what scope do you recommend me to get as a daily driver? This one or one of those usb scopes, like owon hantec?

Mark Garth says:

Great review Mike. I don’t need a portable scope at the moment, so will stick with my hacked Rigol, but like you say, this could become a popular format in a year or two.

dan_tm says:

The mouse input is probably most useful when using the scope over HDMI on an external monitor, I’d imagine.

Alexander Sannikov says:

1:20 lol why do you have ads in russian?

Reed Arnold says:

You commented how you liked that the BNCs were full Metal, but on a mobile unit like this I don’t think that is to code. you don’t have an earth ground reference so you can turn the chassis to live potential and not even realize it until you grab the metal shell of the BNC. Mobile units always have them insulated for this reason. Dave on EEV has commented on this a few times.

ddlsmurf says:

Heh how did you get that phasing heart beat signal on there ?

FireballXL55 says:

Good honest review thanks, if you show how you normally do something and say this is the best way you have found to do it. then it will not go smoothly.
I also open cases your way and usually they will crack open without too much effort.

Zegarac Robert says:

Mike you give them so much feedback, they should send you new scope for free for review every time they make one!

gnomishworks says:

Awesome review! Just picked up the TO1104 (not M) without the battery.

I hope to build my own battery pack and adapter daughter board. Did you happen to measure the pin output of the battery daughter/charger board?

Doc T'Soni says:

Hearing you talk through your nose like that I can almost picture you sitting there in your cold shed all day testing obscure chinese electronics.. Hope you built yourself a nice heater for the rest of the winter or you might have to implement some sort of a nasal frequency cut-off compensation.

Alfred Stampe says:

23:18 looked like you just cracked the screen, but it’s just reflection, phew

Pieh0 says:

42:35 IT’S THE CURRENT YEAR, GUISE! 😉

Knuckles the Echidna says:

Just catching up on your videos, nice scope! All it needs now is a built in bluetooth speaker and patient monitor!

stonent says:

I noticed a 2013 copyright on the startup, so they’ve been at this one for 3 years now. I remember when we were all arguing with their rep that kept posting on the forum when it seemed like vapor-ware.

Moon Moon says:

The nice thing about Chinese companies and Chinese gear is that they do tend to listen, and they’re not really afraid to take risks, which is part of the reason why they can respin things so quickly. I was watching a documentary about this, if someone points out a problem to the manufacturer and offers a solution, that solution can be implemented next week, even if it’s a hardware change.

If Micsig takes feedback seriously and wants to improve their products, I think they should listen to what people like you have to say, and you might just see changes implemented fairly quickly.

Bernard Shreve Jr. says:

I do have to say thanks for spending the time (and money) to do the Micsig review- Mike. I sure hope Micsig can fix the short sighted thought on the fine adjustments; I can not even imagine not implementing this in a scope user interface in planning the design- this is the large issue that needs to be fixed now.

stonent says:

There was a spelling mistake in one menu, Multi Channel was Muti Channel.
