The PropScope is a two-channel oscilloscope that is capable of reading 25 million samples per second with ten bits of resolution over one, two, ten, or twenty volt peak-to-peak waveforms. Power is provided through the USB port requiring only a single cable to connect the PropScope to any laptop or desktop PC.

A built-in expansion port allows additional capabilities and upgrades, by simply plugging in an expansion card. A PropScope DAC card is even included, providing an analog trigger, a four-bit digital trigger, an eight-bit digital to analog converter, and a four-bit NTSC/PAL output.

The included software provides a traditional scope interface along with auto measurements and the ability to store and export waveforms. The software also provides features not normally available in a stand-alone oscilloscope, including a function generator, a logic analyzer, a spectrum analyzer, a vector-scope, and more.
