1013D Plus Oscilloscope - Portable Handheld Tablet Oscilloscope with 100X High Voltage Probe, 2 Channels 100Mhz Bandwidth 1GSa/s Sampling Rate 7" TFT LCD Touch Screen

This is 5th of same one I have bought.... keep giving to customers they're so good! Thanks for great product. The AUTOSET is one of my favourite features. You just connect signal, press autoset, hear relay's clicking - suddenly you have clear, stable display!! It's excellent!!

I've been using this oscilloscope for over a week and finally decided to write a review. The screen is simply awesome . It is not an OLED screen but visually delivers high contrast with a deep black background. . I like the portability. I like the large 7 inch screen normally found on higher dollar scopes. It has been a good scope for measuring pulse switching and logic control which is my main use. When I design PIC micro controller circuits, I like to see the intended logic control results using a scope. I wish it had an optional rubber impact bezel ring. This would give a measure of added protection to the case.

I needed a cheap, portable, “beater” scope to use away from the ‘bench, so I bought this with very low expectations. But I’m actually quite impressed! It isnt a LeCroy, but for 160-ish bucks, its a winner! The best part for me is it can be completely isolated from any ground. Totally self-powered and easily air-gapped to the tune of hundreds of thousands of volts. Of course, the input to the scope’s BNC wont handle more than 40 volts delta without an attenuator probe, so your input differential voltage cant be more than this, but you could hook this up between adjacent windings of a tesla coil and it wouldnt care as long as you had it in a Faraday cage. You CANT do that with a line powered scope, and you DONT want to do this with a $8000 name-brand portable! The user interface is really simple. Nothing but the basics here. Trigger, slope, sweep, volts/division, AC/DC coupling, probe attenuation (1x, 10x, 100x). Thats pretty much it. Nice that it comes with two ea 1x/10x switchable probes and one dedicated 100x probe for up to (allegedly) 4000 v. No, I dont plan on trying it, because it looks kinda manky in the insulation department, but it works a treat on 440 AC! 5/5 stars. Kinda gobsmacked here.

The instruction manual is not clear about how to safely perform high voltage measurements. I bought this to "inexpensively" check the sine wave of my mains, power inverter and standby generator. This type of measurement is safe, as long as you don't touch any metal on the oscilloscope, and nothing with a path to ground touches metal on the oscilloscope. While measuring high voltages, keep it unplugged from the wall outlet and only run on battery power. UPDATE: The included charging cable cannot be used as a data cable to copy screenshots from the oscilloscope. In Windows I got the message, "USB device not recognized. The last USB device you connected to this computer malfunctioned, and Windows does not recognize it." You need a USB-C cable that supports both charging and data transfer.

Not the end all to be all but for the price, you have portability and a quality tool. If you want more, you will pay a whole lot more.

It's ok for cheap oscilloscope, but it has very bad resolution. I use it for inspecting cam and crank signals, including any hall effect type of sensor on cars. When zooming out to see more time frame, it becomes really laggy and slow. Also if you zoom out to 500ms per division, you get rendom spikes that are not caused by actual signal, and the actual wave pattern doesn't show up completely. Moving the pattern on the graph always gets stuck at middle of x axis. I can not zoom out to get a complete 10 second snapshot with details of wave pattern. Most issues happen on DC coupling. For AC testing it's ok. IT DOESNT HAVE VOLTAGE SCALE AT LEFT OF AXIS. ONLY VOLTAGE MEASUREMENT IS MANUALLY ALIGNING 2 VOLTAGE LINES ON GRAPH (INACCURATE). For almost $200 it's not worth it. For AC work it's ok, it can do frequency. For DC work or car repairs, don't recommend

Nice 100MHz 2 channel scope that is lithium battery powered. I used it when I was restoring a Dynaco ST-70, comparing the two channel output.

The accuracy of this oscilloscope is questionable. Voltage readings are off by about 8%. There is significant roll off at frequencies above 85 MHz. I only need it for waveform evaluation or I would give this scope 1star. As soon as I can afford it I will buy a real oscilloscope.
