FNIRSI 1013D 100MHz Oscilloscope, 2 Channel Oscilloscope 7" Touchscreen | 1GSa/s Sampling Rate Automotive Oscilloscope with 6000mAh Battery, One-Click Auto Setup for Car Repair & Circuit Repair

This thing opens up a world of how things work in my various hobby. It's easy to use and feature rich for what you pay for. The portability is just right and screen is bright and clear. The touch panel is also responsive. Battery life is ok to use for a couple of hours.

I have for 10 months this oscilloscope and size is good i can see the waveforms good ,the battery life is ok , good display and portability i can carry any place bc. Not to big and not too small ,is ok for the money if you want something good and you can see to many waveforms i can mesure waveforms sensors camshaft , crankshaft, fuel injectors waveforms and more. I will like put a video o picture but for some reason i can't do it from my phone. But is great this oscilloscope you can mesure red can bus too.

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.

This oscilloscope has such low precision that even I2C signals cannot display accurate waveforms.

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 just received it from Amazon via UPS. I opened it and the first thing I noticed was the on/off button was missing, one of the probes was missing parts/broken and would not turn on. I could still activate the on/off switch where the button was supposed to be but after charging nothing. Returning ASAP!

First got it, it worked okay. It's very limited in terms of configurating measurement settings, but that's what you get with these mini scopes.Not even two years in possession and using it, it's SD card / firmware has failed; don't know why a dedicated ROM wasn't a thing and use an SD card. it's useless once the error shows up as shown.luckily there is CFW available to fix it up. So at least there's that thanks to communities that delve into making things better by taking things into their own hands.

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

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.

tiene una amplia repeticion de ejemplos ( 1 giga ) para no perder el menor detalle, y ademas es bastante facil su manejo, soporta una impedancia de 1x 10x y 100x para alto voltage, ademas que cuenta con proteccion del modulo. con sus dos canales puedes ver la forma de onda tanto del sensor del cigueñal como la señal del arbol de levas conjuntamente

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.
