1013D Oscilloscope

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.

This is a great light weight portable little scope. This is not a $3,000 tech. Scope. At this price it is a great hobby scope. Very nice dual display. Easy to see. The touch display is very simple. Basically put the probe on the test item and touch auto setup. It clicks several times and bingo everything is displayed. It tells you the frequency and P to P and RMS right on the screen. No calculations. I measured my house AC at 124 VAC but the scope said 130 VAC RMS. So this is not a calibration scope. Not sure if there is an adjustment for adjusting the scope to be a little more precise? However if you’re wanting a very small scope that fits in a drawer and lets you see many things this is the best one I have seen. I love it and I have already fixed a friend’s equipment using this little scope. Check your home power with it. Your scope may be better calibrated that the one I got. But it is not a problem for me. I use my multi meter for exact voltage measurements. You will enjoy this little scope.

Good scope for starting in the use of scopes for car repair.... easy to use and lots of online help is available so much better than spending the thousands asked for the automotive specialty scopes and easily adaptable

I've not used this product that much yet. I bought it for a specific reason, and for that it doesn't seem suitable. It's a nice little "gadget" for the price. Probably great for students or somebody just getting started. I'd loved to have had one of these years ago. But, I t was difficult to get started, I just couldn't get a signal displayed. I finally got one though, just hard to set it up at first. Secondly, it doesn't seem to have the low voltage sensitivity I need at the moment. So, I will probably keep using it when we travel in the RV and I don't need a "power scope". Just keep that in mind, 50mV/Div is the lowest, plus, I think the impedance might be a bit low, preventing low level signal visuals. But other than that I like it. I'm sure it will prove useful, at least at the mid-range stuff. I don't think it will capture really fast signals either, but mid-range, seems to be pretty good so far.

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.

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

I have had to rebuild my entire lab due to losing access to my home lab, and I needed to do it on a budget. This 1013D is occupying the same space formerly occupied by a TDS210 - it's a small, medium bandwidth 2ch scope I use for probing vintage computers I'm repairing, and debugging embedded projects based on small controllers like the ESP32. It's fairly low resolution (8-bit DAC) but perfectly adequate for basic inspection and debugging tasks. Instructions are thin but sufficient. It's a fairly versatile tool, but if you want more options you can upgrade to one of their models that has built-in sig gen and multimeter (I have one of those too). It's a little weird to get used to a 100% touch interface if you're used to traditional scopes with knobs and buttons (there's a lot of places where you just have to know where to tap, no onscreen cues), but once you're familiar with it it's easy to operate. I have several other FNIRSI devices and find them all excellent value for money.

This scope works well. It is not a lab quality scope, but who wants to drag one of those to some remote location with a 10 mile long extension cord? Or even a 100 footer? First use was up a 100 foot radio tower. Sometimes once you get something installed, you want to troubleshoot it in the field rather than drag it back to the shop, where you might find that the cabling was the problem. Any military trained tech will be happy to explain the acronym SNAFU if you don't already know it. It comes with a version for polite company if that might be useful.
