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

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.

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.

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

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.

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
