This integrated oscilloscope includes all the basic functions of a laboratory oscilloscope allowing to carry out all the measures and tests needed.

For this project an integrated oscilloscope is created which uses the board SMT32F769I- DISCO with touchscreen and a HW circuit that can be connected to an expansion board for the arduino interfaces.

The device developed allows to measure three analog input channels and four digital input channels, view and generate the analog output, generate a 3.3V PWM Vref signal, record data on an SDcard (track recording and screen saving in .bmp format), download data from Sdcard to the PC via USB and adjust the different functions of the oscilloscope via hardware interface (keys, encoder, TouchScreen).

Some interesting results:

-3 input channels 2.4MSPS
100Vpp Interleave Triple ADC mode: 7.2MSPS
External trigger: 0-15VoltI
Analog Output: 1MSPS – 10Vpp
4 digital inputs: 40MSPS – 5Volt tolerant
OutRef PWM: 100MHz – 3.3Volt
