  • Great product for Sunday's Electricians

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:

    - It's tiny and cute ; fit perfectly in a pocket

    - Came with two probes (x1/x10 for high frequency signals and another one for use with a breadboard)

    - It's OPEN-SOURCE ! You can easely find examples of code and compilator to customize your DSO (Add XY mode, FFT view, increase performances, or play Snake...)

    - LCD Screen is very bright, and there is a buzzer inside of the product

    - You can save waveforms in a lot of formats : BMP, CSV (to use with Excel)

    - Autonomy is very good due to the high capacity battery (1000 mAh)

    - The DSO seems to be built with high quality materials.

    - The signals generator can produce a lot a kind of waveforms, up to 8 MHz

    - You can setup logical operations between the two digital inputs (AND, OR), and mathematical operations between the two analogs inputs (+, -)

    - The Trigger works pretty well !

    Cons:

    - Like I said before, the device is very tiny. For me it's an advantage, but others people may not like it.

    - The probes connectors are not as common as true oscilloscope connectors. Maybe DX should sell some adaptators.

    - The signal pin inside the probes connector is very skinny and can twist easily.

    - I have not received the USB cable that was mentioned on the page.

    OtherThoughts:

    If you need to know what's happening in a circuit, this device is for you ! Of course, for the price, you cannot expect the performances of a true digital oscilloscope, but remember that the DSO is 10 times less expensive !

    Documentation says it's able to get signals up to 72 MHz, but in reality, this number is the rate of samples / seconds. So I prefer to say that the max frequency of a signal to be analysed is ~10Mhz.

    Maybe the device can be delivered without calibration. Don't worry, there is a automatic calibration mode in the setup menu :)

    Bottomline:

    If you dream of sinusoidal waveforms all of the night, don't wait anymore : BUY IT ! You will not regret it ! :)
