PPMScope is a do-it-yourself oscilloscope with an open source design. The
intent is that the project can be constructed by an electronics hobbiest using
the instructions included. The design is a compromise between features and
cost. The bandwidth is lower than a commercial scope, so it's use is limited
to signals of 500 kHz and below. It's sample buffer is also smaller than
a commercial scope, however sufficient for most oscilloscope functions.

This is a version based on the PIC16F877A microcontroller running with a 20MHz
clock. The maximum sampling rate is 1 MHz with a 5 Mhz equivalent sampling
mode. Currently, the computer interface supports USB, serial, and parallel ports.

Good luck on the construction and I hope you enjoy your oscilloscope. I am
happy to answer any questions or provide technical support for this design.

User Reviews

  • Serious project written in PIC assembly and C with all the schematics and docs. Useful when you need 500 kHz oscilloscope with 2 channels, spectrum view (software), trigger or just want to learn how analog part of oscilloscope works.
