FNIRSI 2C53P Handheld Tablet Oscilloscope Multimeter DDS Signal Generator 3 in 1, 2CH Automotive Oscilloscope Multimeters with 50Mhz Bandwidth, 19999 Counts, 250MS/s Sampling, 4.3 inch Touch Screen

So my purchase began with a 10.1 inch digital microscope. I thought it would be nice to have an oscilloscope and multimeter mounted to the same frame, so I set out looking for what was available. I eventually stumbled on this and I am very pleased with it.I have several different oscilloscopes including high end name brand stuff. I don't really expect professional engineering level out of the little DSOs like these, but they are handy to have around for the portability and I find myself using them more often than my professional scopes.This guy is feature packed and has all of the things you might need in a little impromptu troubleshooting or reverse-engineering session. You get the scope with a generous bandwidth and two channels, a full function DMM, and a signal generator all in one little compact unit. Geeze, if it had a light duty 0-5V power supply built in, you probably wouldn't need much more.This one is going to get mounted semi permanently to my microscope boom, but I may eventually grab another to keep in my mobile toolkit. I showed the other engineers at work and a few of them have decided to buy one.

I honestly got this strictly for CAN monitoring, but it does well as a multimeter as well as an oscilloscope. Voltage and resistance seems dead on with my fluke, so accuracy seems good. I like the design and layout, it’s super simple to use. Battery life isn’t a concern, and I haven’t had tor recharge it yet. The size is perfect for poking around under the dash, and if it holds up well I’ll snag the 7 inch version down the road.I also really like that when measuring voltage, it has a histograph of the voltage readings on the bottom of the screen, and lets you see voltage from the last 10-15 seconds. Really nice feature I didn’t think I’d like as much as I do

Kind of finicky to work with and haven’t really explored of all of the features, but so far so good. Great option to have something portable.

Other than battery life being a little on the lesser side it’sa reallygood meter

Bought two of these. First one did not work, always a signal on CH2 Scope input. Returned it and bought a second one worked, but will does not meet spec by like 100:1. 50Mhz band width and sample rate, no way. 50Mhz on Amazon, 20Mhz in the manual, and even that was not close. Could not keep up with a 100Khz signal. Compared it side by side with my bench scope, and a cheaper DVM style my friend bought. This signal on this one was terrible. The DVM style matched just fine to the bench. It could not keep up and it looked like there was no signal at all. Really liked the touch screen user interface, really liked the larger screen and tried hard to figure it out and make it work. Much easier to navigate . Returning #2 and unfortunately having to buy The DVM with smaller screen and button interface

Worth the money.

I am new to oscilloscopes but have spent a lot of time following automotive channels that use portables ones. Am learning the ins and outs of this tool but, it is missing something that I can not find and that is the speed the data is displayed. Am unable to slow down the display and look close at the wave for key points of interest..It’s not a bad scope, it’s a good scope for select purposes. Am returning this one and going with the more expensive one I have seen in use with features that fit my needs.

I am a traveling EE consultant, and this is a fantastic tool to have in my backpack. Yes, you can get a better scope, multimeter or signal generator. This is a fine, compact tool that has all three. It's going to stay in my backpack. The only thing I wish it had that it doesn't is µA measurement for low power applications.A couple things to note: My unit did not come with the carrying case or the signal generator cable. I messaged the company through Amazon and they shipped me the missing components. The carrying case is very nice, by the way.Also: To set the trigger level, there is an arrow on the right side of the screen that you adjust with your finger. This was not intuitive, but I asked the company through amazon again and they answered quickly.I would recommend to anyone who wants this type of functionality in a compact package.
