    Definitely petite. As supplied the DSO188 is usable up to 40VAC and the input socket is NOT BNC. To make the O-scope really usable a 10X probe is needed. To do so you will have to order a BNC adapter (#930139) & a 10X probe (#1157645), you will then be able to monitor voltages up to 600VAC. Very handy size & with built-in battery it is a convenient test tool you can actually keep in your pocket. Not for precision work but you can trace signals in audio, video & automobile circuits for troubleshooting. The O-scope is shipped with Chinese instructions, you will have to get Bang Good to E-mail you the English version. All-in-all it's worth the price.

    With its dimensions of 57 mm by 34 mm by 11 mm, the DSO188 by Daniu can be called a matchbox oscilloscope. If you think this device is nothing more than a fun but useless toy, you are wrong. You can effectively observe signals up to 100 kHz. Of all the cheaper than fifty euro scoops that we have tested, we are most impressed by this DSO188. Despite the small dimensions, the scope is easy to operate and the oscillogram is easy to interpret. Even with the life of about ninety minutes with one battery charge, you can live well in practice. The only unfortunate thing about this beautiful device is that the DSO188 can not be used to reliably measure the numerical quantities of the input signal. The manufacturer had better omitted this option, because with a measurement function that is 'for reference only' you do not have much in practice.

    This is a really good matchbox size DSO that works as described and fits perfect for my small scale voltage DIY projects. Leaflet manual provided is tiny also so i scanned -took a photo of it and reprinted it on A4 size to have a readable version. A 10x probe like is needed to get full functionality of it. I connected one of them using the BNC turn MCX switch head came in the box and made some tests - c photos - using DC test signals of DSO150 15001K Digital Oscilloscope ( and AC power provided by Intelligent Screen Pure Sine Wave Power Inverter 12V To 220V 3000W ( I tested all keys functions and it works just perfects. Waveforms and infos are displayed clearly although the screen is small size. I want to use this DSO with AC grid voltage so i made a plastic cover using thick packaging transparency that is hard enough but also flexible to let press the small tact buttons (a transparent printing sheet might be used also) and Visbella Universal 5 Seconds Fix UV Light Glue ( forming a small box, i made 3 holes for probe, usb supply and on-off switch and it was ready !!! So now i have a full functional high voltage protected version of this very good quality DSO ! Shipping and delivery was very fast (11 days China to Greece) as usually with Banggood. Satisfied once again !

    Frequency can be displayed, Vmax, Vmin, Duty, Vrms, Vpp. At any time, the waveform display (pause function) is frozen. Battery/USB power supply, built-in 250mAh battery and intelligent charge management. Ultra small volume, easy to carry.

    Smallest Oscilloscope with good quality. Good product . Recommended.

    A usable device to look at lowish frequency signals but the input impedance is very non-standard. The spec states 1 Mohm but mine is just over 500 k and 170 pF. x10 probes are designed for 1 Mohm and around 20 pF so take that into account if using a x10 probe.

    Hobbi célra tökéletes. Nem egy labortáp, viszont kicsi és könnyen hordozható, az akku is elég ideig bírja szusszal. A hozzá adott krokodilos kábel túl sok zajt tud begyűjteni, ahelyett érdemes egy rendes mérőfejet beszerezni. A mért jelalakokat, frekvenciákat elég jól visszaadta. Minimális torzítást véltem felfedezni, de hát mint mondtam nem egy laborműszer.

    Small, simple to use and handy DSO. May need to use an appropriate enclosure for field use.
