This portable two-channel digital storage oscilloscope made by Parallax, is a handy and affordable tool for both the hobbyist and student. Three pairs of probes connect to the compact powder-coated aluminum case, two for signal channels and a third for external TTL triggering. The hardware connects to your PC with the included USB cable for both data transfer and power, so no external power supply is needed.All oscilloscope controls are managed through one of our two software interface platforms. Both platforms include classic scope features such as Auto and Normal trigger modes, variable trigger voltage, external triggering, and auto-measurements (Min, Max, Frequency, Period). Three easy-to-use cursor functions to measure acquired signals manually, with the option to snap to the waveform. Each platform also allows you to save customized setups, and to export data and bitmaps for analysis and inclusion in reports.

The activities in Understanding Signals v1.0 require the Parallax USB Oscilloscope
software version 4.0, which runs on most Windows 2K and XP operating systems. The Parallax USB Oscilloscope Software Version 5 (right), which runs on most Windows XP and Vista systems, does not fully support the activities in Understanding Signals.
