Any chance you can plug in a USB stick and grab screenshots? That's mighty useful and I don't want to have to connect up a laptop via USB or Ethernet just to capture screenshots. It says you use a mouse so I presume it has at least one USB port.

The micsig is an Android tablet, it runs Android apps (the oscilloscope is just a built-in app!)

This video is quite informative:



For "four channel portable 'scope" I don't think you do better than that.

(hell, I'm not even sure you can do much better in a desktop 'scope in that price range...)

1. E Plus has more acquisition memory.  C has 28MS total, E plus has 70 MS total. To me not worth doubling the price. All else is same AFAIK.
Then I agree. Not worth the price just for extra memory and waveform acq speed. Thanks for the confirmation.

2. Best view angle is at right angle or slightly above.  It has stand in the back that puts it at proper angle when on desk.
If the stand has it "leaning back" from straight up and down, then they presume your head will be above the scope, correct? Hence the comments about being "tall enough". I think I understand. The poor visibility would occur if your line of sight is below perpendicular of the screen. Do I have that correct?

3. It feels sturdy and good quality. Encoders are nice and firm. It has no major problems, but it's basic scope. It has no AC RMS measurement. It has no measurement statistics. You have table mode for decodes but only full screen. So it's ether graphic mode with waveform or table mode. You can't switch between graphic and table decoding without loosing data. There is no segmented memory. CAN is only basic CAN, there is no CAN FD.
That's OK, not buying it for protocol decode (have other solutions for that when necessary).

All in all, what i has works very well, it is good quality, battery runs for 5+ hours and is well worth the money for what it is. Question is : is it enough of the scope for you?
Sounds like it will do the job! I need a digital storage scope with four channels that can display analog waveforms to a few 10's of MHz. Traditional triggering is adequate. The ability to capture four signals and then zoom in/out and back/forth pretty much covers it. And it runs on a battery for 50%+ of a working day. If it's rugged enough to last a while - and it sounds like you think so - then we have a winner.

Hello!
just a quick recap

1.  :-+
2. Something like that. Mind you, it doesn't get invisible if you are below center line, but contrast starts washing out quickly. If it is on a shelf above you it's not that good. On a desk it's great pretty much anywhere. Word of warning, I'm 6'5"... :-DD
3. Protocol decodes do come with scope (check with dealer, in EU they all come free) and they work OK. In table mode you can interleave 2 decodes so you can see them in coherent time...
4. USB ? Sure it can. You also have internal 8 GB and can save REF traces, captures, screenshots and videos... Yes MP4 of something going on on the screen. It also has Ethernet and WiFi, and you can install internal FTP server so you can grab stuff from the PC directly...

Some other comments... It has very nice implementation of color grading, boots quite fast, BNCs are on the top (I was afraid they would get in a way but it's fine), you have a over the hand handle on left side to hold it safely, it has HDMI out (it looks great on 42" TV). Charger is powerful and seems good quality mechanically, but it's electrically noisy. A replacement medical grade PSU is recommended if you want to work plugged in. Battery is user changeable and available as spare part.

All in all, very handy little thing that seems to work just fine for a "grab and go" situations.. I have for half a year and it already paid itself off in just few interventions, where we could diagnose problem on the spot and just replace failed modules, instead of unmounting whole device and haul it back to office for diagnostics...
