FNIRSI 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 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.

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.

Good value, pretty accurate readings compared to my pico and hantech scopes and it’s quick and easy to use. Limited features for storing waveforms but that’s not my main reason for the purchase.

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.

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.
