Three-axis accelerometer and oscilloscope interface
The PP877 is a MEMS-based three-axis accelerometer and oscilloscope interface. It is supplied with 3 short BNC to BNC cables which plug directly into any PicoScope oscilloscope with 3 or more analog channels. High-resolution oscilloscopes such as the PicoScope 4000 Series are recommended to take advantage of their increased sensitivity.
