About: Digilent Analog Discovery 3 USB Oscilloscope

Digilent Analog Discovery 3 USB Oscilloscope is a portable USB-powered test and measurement device, though it now features an upgraded USB-C® connection. It’s lightweight and small enough to fit in your pocket or backpack, so it becomes an exceptional companion for any engineer.

The Analog Discovery 3 boasts a larger-than-ever buffer size, allowing more data to be sent through the waveform generator and received through the mixed signal (analog and digital) oscilloscope. It also has an increased sampling rate of up to 125 MS/s on all channels and a more potent power supply (up to 800 mA). The larger buffers allow you to capture longer records at high resolution and enable more complex AWG signals. Modulated AWG signals also take advantage of larger buffers, and more complex modulated signals have been added including phase modulation and summation.
