Xprotolab - Miniature Oscilloscope and Waveform Generator
January 01, 2011 09:08PM
I'm developing a fully featured, low cost, MSO. Schematics and HEX files available if you want to build your own unit.

The Xprotolab is the first mixed signal oscilloscope with an arbitrary waveform generator in a DIP module. It measures only 1.6" sq. inches, and can be mounted directly on a breadboard. The Xprotolab can also be used as a development board for the AVR XMEGA microcontroller.

General Specifications:

* ATXMEGA32A4 microcontroller: 32KB Flash, 4KB SRAM, 1KB EEPROM
* Graphic OLED display 0.96", 128x64 pixels, wide viewing angle
* Module size: 1.60" x 1.00"
* PDI interface
* 4 tactile switches
* Micro USB connector for power (Software USB will be a future update)

Oscilloscope specifications:

* 2 Analog Inputs, 8 Digital Inputs
* Maximum Sampling rate: 2MSPS
* Analog Bandwidth: 318kHz
* Resolution: 8bits
* Input Impedance: 1MΩ
* Buffer size per channel: 256
* Max. Input Voltage: +/- 10V

AWG specifications:

* 1 Analog Output
* Maximum conversion rate: 1MSPS
* Analog Bandwidth: 66kHz
* Resolution: 8bits
* Low output impedance
* Buffer size: 256
* Max. Output Voltage: +/- 2V
