USB Accessory Oscilloscope APK for Android

The USB Accessory Oscilloscope is a free Android application designed to enable users to view, measure, and capture real-time waveforms. This educational tool is an enhancement of a previous version by Jeremy, providing precise measurements of frequency, Vpp, and DC offset. Users can work with a frequency range from 0.1 Hz to 20 kHz and an input voltage capacity of +/-1 mV to +/-20 V, ensuring versatility in various applications. The application boasts an ADC resolution that varies from 8 to 10 bits, depending on the sampling rate, which can reach up to 50 kHz. Additionally, it offers 16 time/div settings ranging from 5 seconds to 50 microseconds and 10 voltage/div options from 5 V to 5 mV, making it adaptable for different user needs.

Powered by a micro-USB cable, the USB Accessory Oscilloscope not only connects seamlessly to Android devices but also supplies charging power to the device while in use. This feature is particularly beneficial for extended usage, allowing users to maintain their devices charged while conducting measurements. The application serves as a handy tool for students, educators, and professionals interested in electronics and waveform analysis, making it a valuable addition to the educational software category.
