OWONVDS1022 USB Oscilloscope 2x 25 MHz 100MS/s

Works great easy to set up

Like most truly useful and versatile tools there is a learning curve I'm just beginning to climb. I got it plugged in, set up and calibrated ok with only minor glitches. This may be software related. I run Linux on my laptop and the third party port of the user interface has not been as thoroughly debugged as what ships with the unit for use on Windows or Mac. More likely it's just user error and will go away as I develop a better understanding of what I'm doing.I had to drop a star for portability, not because of any fault with the unit, but simply because it needs to be paired with some sort of computer. I'm sure eventually somebody will develop an android app, allowing it to be linked with a smart phone or touch pad and external battery for a compact and portable unit.As long as it is used with a laptop running off of battery or a two wire non-grounded power supply it operates as a "floating" unit and the lack of usb ground isolation is irrelevant. This gives a nice discount from the more expensive 1022(i) model. This is the least expensive scope of it's type that does the signal processing on internal hardware, using the usb mainly for power and low bandwidth communication to the computer running the display application. It's a real usable tool offering the best deal I've found for the money.

Emballage baclé matériel en bon état.Juste ce qu'il me faut pour mes bricolages electroniques !

Very Stable O scope. I really like the probe calibration function built into it

For the price, if your looking for an o-scope with general needs, this may be just fine. However, the noise it produces because its not the isolated USB model, you cannot view very low voltage captures and needs to be in a very low noise environment. The software was probably better than others, however its still very poorly done and all of the manufactures continue to neglect putting enough time and effort into their USB o-scopes software. Currently still not Windows 10 compatible, although I was able to get it to work for a couple sessions and then quit completely. The measuring data was extremely out of calibration, even so i ran the calibration tool over and over.The thing I was happy with was the probes the unit came with.

bonjour très bon produit pour moi est pour débuter

ok

Very good two channel oscilloscope. Good for electrophysiology and setting gup and using was easy.

Phytonを用いて計測システムを組むのにSCPIプロトコルが開示されているメーカで安い物を探していたらOwonにたどり着きました。　他のPCオシロも複数台所有していて原理開発に用いていたのですが、SCPI関連の資料が十分ではなかったのでこちらを購入しています。　サポートは中華メーカの中で良い方なので、気になる方にはお勧めです。

かなり昔に買ったDDS-140という古いUSBオシロスコープを使っていましたが、クロックのような連続波形はトリガできて波形が見えるが、SPIのデータ信号のような単発波形はトリガできない問題がありました。VDS1022は、単発の波形をシングルトリガで取得することができました。購入した目的は、マイコンのUART信号やSPI信号のビット列を確認するためです。シングルトリガで波形を取得できてビット列を確認できたので目的を達成できて満足しています。マイコンのソフトデバッグに重宝しています。★4個なのは、ソフトウェアがちょっと使いずらいためです。
