With this device, you can use your computer as a digital, sample-storing oscilloscope, which gets an essential utility of your electric measurements. The power for the BlueDSO device is supplied via USB, so you won’t need any other power adapter when using it with your computer.

Don’t have a computer nearby? Android-based phones and other devices can make use of the BlueDSO device, therefore it can be used with a phone or tablet without a computer. In this case, power has to be supplied via a standard USB phone charger or a car outlet USB adapter.

The oscilloscope is the most frequently used, most flexible device for electric measurements. It visualizes an electric potential over time function, producing much more information than other potential and current measurement methods.

With an oscilloscope the following quantities can be either directly or indirectly measured:

direct voltage, alternating voltage, direct current, alternating current, time, time delay, phase, phase difference, frequency

With an oscilloscope the shape changes of an electric signal can be observed, both it’s direct and alternating current components can be measured. With a multi-channel device, you can inspect and compare more electric signals at once.

In many cases, electric signals’ complex mathematical analysis can be performed with a digital storage oscilloscope.
