The DSS-31 oscilloscope is a standalone portable device with a graphic display and microcontroller control, and is designed to study electrical signals in the frequency range from zero to several 1MHz.

The oscilloscope uses Anti-Aliasing technology, which reduces the discrete distortions of the waveform and brings the signal display closer to the typical analog oscilloscopes.
