About this app

Android Bluetooth Oscilloscope.
It can be used on any mobile device with Android, Windows or Linux PC (Mac is coming) system using Bluetooth technology. It means that there are no any wire connections to your phone, tablet or PC, which can guarantee the safety of your mobile device or PC, plus portability.
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 to view live waveforms, make measurements.

Math channels

System can display up to 5 math channels.
• Main operations: +, –, ×, /, sqrt, x^y, exp, ln, log, abs
• Trigonometric functions: sin, cos, tan, asin, acos, atan
• Additional operands: PI, T (time)
Math example: exp(-T*125)*sin(2*pi*1000*T)

Control the following functions

• start/stop/single acquisition
• change time/div
• change volts/div
• turn channels on/off
• select trigger type/level
• screen zooming
• full screen mode
• font size
• signal retention level
• double click on triggers sets them to zero level

Ratings and reviews

Not giving a perfect square wave. Frequency and time calculation is accurate. When I give 25 Hz 20%duty cycle it does not show on time at 20% instead it shows 50% square wave with clippings. Please give the correct probe ckt diagram for mic input. Thanks for a good scope app in playstore. RK seth.

I am especially pleased with the design and the performance and expansive utility of this application and its associated hardware module. Notably very good work, guys.

Controls are very good but I have not tested calibration and accuracy of maths functions.
