YEAPOOK ADS1014D 2 in 1 Digital Oscilloscope DDS Signal Generator with 2 Channels 100Mhz Bandwidth 1GSa/s Sampling Rate (ADS1014D)

This scope does what it is designed to do. It is a basic scope that has basic settings, so if you need a scope with more accuracy and a true 100mhz this is not for you. However if basis needs and portability is what you are looking for, this is a scope to consider. I plugged this into my battery pack and it worked just fine. The 150.00 to 175.00 range is a reasonable price, however anything above this you can add a few more $$$ and get a more featured packed scope.

Love the size. Would be better if there was a battery for about 1 hour runtime. Interface difficult to learn. Not like any scope I ever used. Menus hard to figure out. Only thing that didn't work properly is the frequency display

Nice for the price. Custom waveform gen is interesting, albiet a bit tedious to get your desired waveform.Some buttons are behind menu buttons.but overall very nice, it uses 5v power from a wall wort, meaning that it isnt referenced to mains ground like some scopes. So you dont need a differential probe. Which run $200.Connecting it to a pc just lets you look at pictures, thats it. But if you take the scope apart, there is a 8 gig SD card with those waveform pictures,it can be removed to transfer photos. But you gotta take it apart, dunno why they didnt put the sd card on a side where you can easily remove it.but For $200, it is well worth the cost, gives you a 2 channel and a function gen. Other scopes that have this are twice the price.

It is just that, a hobby scope, nothing more. Surprisingly, for the price you can't beat it, as far as I know. Quick -n- dirty boot up, measure time and levels. The main reason I purchased this one was for just that and a built-in function generator. Bright LCD. Less bench top clutter. Having used very high-end scopes costing tens of thousands for the past 20-40 years, if this lasts a year it's well worth it. Can't say anything about support. Hope I never need it.

I really liked the display. Nice and bright. Menus were easy to understand. My plan for it, is for my garage to work on my vehicles. I can also see using it for some of my microcontroller designs. I have already used the Gen output to chase a bad wiring harness on my 95 Miata. The Gen has no DC offset, but I was using it for signal injection only to follow the wires to and from. Great buy for the money!

You need considerable experience with using an oscilloscope before tackling this box. It has many useful features such as a digital readout of the voltage and frequency of the waveform being observed. Since many of the settings/features are accessible through pull down menus, it takes a lot of practice to learn how to access. Older analog scopes use dial switches to set voltage/scale unit. Sweep timing.unit is visible in a tiny screen window. The probes provided have a convenient switch for X1 and X10 settings but one must remember to change the scope sensitivity to match the probe or it is easy to miss the true input value. Some strange waveforms have been observed giving the appearance of random noise on the waveform. Is this a phenomenon of a sampling scope or not? No hint in the manual of a scope sampling charastics?The biggest shortfall is the user manual. It could use more detail on the settings.For the unit’s cost, there is a lot of capability within but you will have to learn the “how-to” with little user manual help.

Good work !!

The signal generator doesn't have an amplitude control.Good simple digital scope for the price.

I’m still dubious about support: I’m pretty sure this is a re-badged FNIRSI model, but I can find no web-presence for Yeapook (downloadable user guides/firmware updates if needed). At the price I think it’s hard to beat. Annoyingly, it came with a Chinese power adapter (easily fixed - it needs a typical, isolated, 2A+ USB supply). After reading a number of reviews (mostly FNIRSI) I gave it a quick checkout. It’s not the most accurate - less so as you get towards 100MHz (but a 100MHz scope only reproduces sinusoid fundamentals near the limit, so you can’t expect it to recreate a 100MHz square wave). I was also worried about reports of wildly inaccurate measurements, but so far it looks quite good (just make sure the probe info is set up properly, and that you aren’t using too slow a timebase and actually looking at an ‘aliased’ signal reconstruction). I do find CH1 seems to have a little inbuilt overshoot (after adjusting the probe). For the price I have an extremely good, hobbyists diagnostic tool with a useful signal generator (& - unless I can find a way to extract/analyse the data - pretty pointless FFT analysis)

Seems to meet the specification in full. As a dual trace oscilloscope it works extremely well, and the Auto button saves a lot of setting-up time. The signal generator has the most amazing range of waveforms and can copy a trace or part of a trace. The FFT function translates into frequency domain, although the trace isn't expandable.On the down side, given the price it's not surprising that the controls are multi-functional and take a little getting used to. The power pack wouldn't plug into a universal adaptor and so I used a phone charger instead.All-in-all, I've very satisfied with my purchase so far.

This is a very good unit for the price easy to use its similar to the Chinese made american brand scope I use at work the auto button makes it easy to use has a large clear display and useful function generator comes with probes and instruction book only bad thing is the supplied mains usb adaptor has non standard chinese pins so I use a spare usb adaptor very good for general hobby use promo delivery from amazon

This oscilloscope was a little tricky out of the box. Firstly, the included power supply was of the 2 prong variety, but this was expected as mentioned and photographed. The manual prohibits using other power supplies, but I found no issue with a high-quality mobile phone charger.I also ran into (and overcome) two further issues out of the box. Firstly, I was unable to get the trigger function to work reliably, but this was resolved by updating to the latest 'FNIRSI' firmware (this is a rebadged FNIRSI 1014d). The second trouble I had was that channel 1 was reading far too low on the 1V scale, this was caused by a sticky relay, and rapidly switching the voltage div knob fixed that. (See photo for the wave)It is great that this oscilloscope can operate from an isolated 5v supply, it makes measurements of signals that reference a non-earth potential possible, though a little dangerous. The integrated function generator is nice to have, it would be even better if it had a level control for it, as it is a 5V signal.

I was unsure about ordering due to some of the UK reviews saying that the power adaptor was low quality. The one I received didn’t have any UK adaptor at all - just a USA one. However, all it needs is a 2Amp USB A power supply! That aside, it looks like a quality bit of kit for the price with decent probes. I was particularly impressed with the screen quality and menu system. So far I have tested on basic sine waves and PWM motor controllers and it looks accurate enough for hobby use. Very impressed for the price!
