FNIRSI 1013D Oscilloscope - Handheld Tablet Oscilloscope, Portable Digital Storage Oscilloscope Kit 2 Channels 100Mhz Bandwidth 1GSa/s Sampling Rate 7" TFT LCD Touch Screen

Nice oscilloscope for tons of uses. Shipped overnight, which was impressive. I used it yesterday to do a relative compression test on a friend's car to diagnose some engine misfires. To do this, I connected the probe for channel 1 to ground and the signal wire to the cylinder 1 ignition coil. I connected the channel 2 probe to the battery positive and negative terminals. After futzing around with it a little, I was able to record a relative compression test, ruling out anything mechanical on the engine (similar voltage drop for each compression stroke). I really like how fast this scope is and how sturdy it is. I have plenty of other uses for it and am glad to have this tool around. The touch screen is also very cool. Great price and fantastic scope. Just wish it came with a case.

It works very well and it has an amazing amount of features. I have, and I am used to regular industrial oscilloscopes but the tablet is very convenient since it is internally powered for field use. This was the second one that I bought for a different project.

I found this scope 1013D somewhat useful for troubleshooting some issues with LED lights in the field. But the GUI is non-intuitive and buggy. And I found the triggers to be unreliable. Then I found some nice people have modified the firmware and improved it greatly. Search for the forum on EEVBlog for this scope "fnirsi-1013d-100mhz-tablet-oscilloscope" for the improved firmware.

Size is good and very accuracy is good and good price for the money and quality is good and very durability is good and

This is an unbelievably smart way to build a scope! It’s the same display as on similarly priced scopes that include dozens of buttons, and it does the same things just using the touch screen. If you can operate a smart phone or iPad, then you can operate the scope. Play with it a few minutes and you are able to start using it. This is the first fundamentally different user interface for a scope since they were invented, and it really works. The scope performance is pretty standard for this price range, it has all the standard things, and it lack a few: difference of ch1 and ch2, more vertical sensitivity (only goes to 50mV per div), FFT needs scale values for vert and horiz and variable resizing so it can be read when needed. Those are suggestions for next generation improvements. You can’t believe this scope when you carry it around and operate it. Highly recommend.

I noticed a few SW bugs with the product, disappointed that they do not have a easy way to update the firmware. The scope does what it advertises. It was a fun experiment but, I suggest people to spend $100 more for something better.

Great little scope. Been using Tektronix scopes for years and this one was very easy top pick up and start using. The touch screen feature is unbelievably better than my old Tektronix TDS 210. Very easy to navigate and a very well designed user interface. I needed a cheap portable scope fast for a trip and am amazed at what I actually got. This may end up being me go-to scope for almost anything that only needs two channels and 100 mHz. I don't know about the accuracy yet and don't know if it will hold up over time but it feels pretty solid so I think the case can take some abuse if needed.

Excellent device for a beginner, works well. Also nicely built with quick touch responses.

Pros: - iPhone-quality touchscreen, very responsive and impressive for this price point - Simple interface and intuitive to use - Works with x1, x10, x100 probe (up to 4000 V with x100 probe). - Holds charge well. Easily lasted over 4 hours with brightness setting turned down to 20% (still plenty bright). - High quality screenshots images that can be transferred over usb to PC - Voltage accuracy seems to match the +/-2 % spec. A 10 V DC supply (confirmed to be 10 V with a DMM) showed as 10.2 V on scope. - Frequency seems very accurate, wall outlet measured 60 Hz (North America) Cons: - Manual trigger setting (Single/Normal) only works when time divisions are set to 50 msec or less - Voltage and time cursors only work at time divisions of 50 msec or less. This doesn't make sense to me? Why can't we use cursors at longer time divisions? - MEAS values (peak-peak voltage, peak voltage, rms, duty cycle, etc) only work at time divisions of 50 msec or less. - Scope seems to miss a bit of data at times if the time division are too large. In the attached image, there's a gap in data in the teal colored waveform PWM signal when there should be data present.

Working well.

Calling this a 100 MHz bandwidth 1 GS/s is an outright lie. It as at most 20 - 25 MHz bandwidth and the sampling rate is certainly no where close to 1GS/s. Otherwise, a good oscilloscope for the price and form factor. Certainly not lab equipment, but good enough for field work.

Item is a used one. Not good scratch have seen out side. I need an unopened pack. Not a trialed returned one.
