【FNRSI 2C53P Plus Upgraded with Carrying CASE】 3in1 Oscilloscope/Multimeter/DDS Signal Generator Tablet Touch Screen Portable Digital Automotive Oscilloscope 2 Channel 50MHz Bandwidth 250Ms/S Counts

This is a very nice device. It provides basic functions of an o'scope as well as other functions. To the reviewer who complained about not having some high end functions you would need to spend five times or more than you paid for this! It is worth buying especially if you are a hobbyist or repair electronic devices at home.

Very handy instrument, the display is large and bright and the menu system is easy to navigate. It is light weight and rechargeable so no power cord to deal with. It comes with a case to store the instrument and its attachments which is good because there are a lot of attachments. The multimeter measurements are accurate as are the calculated values in the scope mode. Overall, very impressive instrument.

It's not as powerful as pico, but if your looking for a cheap basic oscilloscope to give a picture then this is what your searching for. Also has a voltmeter and signal generator. I've been using it at my dealership for random diagnostic and it's impressive. When I don't feel like digging out pico an fighting with setup of it. This is quick and simple to use. My knowledge of using oscilloscope is still entry level, using pico can be frustrating and time consuming. Time is money on flatrate repair. No money in diag if you cannot get it done quickly. Flat rate pay sucks on todays modern highly technical vehicles, cars have changed but we are still paid from a system old as WW2 but thats a different topic. When all you need to see, is there a signal present. This product will give you that and more. Great display, bright,touch screen, auto settings, even the multimeter is auto. Great tool to add into your arsenal of diagnostic equipment

The media could not be loaded. I'm an auto tech and been using this for a few months now. I gave it five stars for being an incredible value. It's a bit light on features compared to more robust portable scopes and scan tools. That said, it's worth it just for the graphing multimeter capability alone. The scope features are generally good enough to identify any problems, or at least get to where you might need a better tool for a deep dive. Very compact and portable, and long battery life. Works well with many of the available multimeter lead and back probe sets available separately. No regrets! The attached video is a coil primary pattern showing some defects.

Works great always use it.

In a time not too long ago, a dual channel osciliscope, waveform generator and multimeter would be bulky and may or may not be portable. I'm impressed. For giggles, I verified the unit based on my known bench standards and came away pleased with the results. Yes, there were some minor variations here and there, but nothing to write home about. A good tool for the bench for sure! The feel of unit seems to be built well, but may have some issues in dusty or dirty environments, a downside of touchscreens. Not sure how the unit would survive being dropped on a hard floor, I need to be careful using it in the field. The manual for the unit is a bit lacking, however, with my background and playing with it for a few minutes filled in the blanks. The only downside for me was thickness of the unit, thinner would fit in the hand better. In conclusion, overall I think it is a good value for the money and hopefully I receive many years of service. Enjoy!

This is a very useless device, the software is full of bugs. Not worth the money. I wanted to use it as a mobile scope when I'm not at my desk, but it's totally useless.Trigger is extremely finicky. Signal is analyzed based on what's on the screen, not the input data. Depending on your zoom level it might or might not catch an edge. Normal trigger keeps auto-triggering. Trigger has a delay of several 100 ms and triggered point is often out on the right side when zoom > 100ms/grid.Using 1x probe the cut-off is around 4V if V res is <5V/grid. If set at 1V/grid, any signal will lose all data over 4V.The 2 scope channels and the signal generator are internally grounded together so it's not possible to use them in situations where on a circuit they need to be hooked to different ground levels.If you set the signal gen to increasing step wave 100Hz 3V and hook the signal out to both scope channels, set V res to 2V on both channels and H res to 2ms. Disable CH2. Set trigger on ch1 at around mid-point (1.5V) for up edge and you get a nice stable image. Now enable CH2. Nothing else changed (trigger is same etc.) and suddenly the signal starts dancing left and right randomly about 2-3 ms (1-1.5 grids) . Turn CH2 off the nice stable image is back.

the ground tester broke very easily I hope i can find replacements. also ,there is a slight lag before the unit beeps when testing continuity
