gds2000tools is a set of command line tools for using the GW Instek GDS-2000 series of oscilloscopes (GDS-2062, GDS-2064, GDS-2102, GDS-2104, GDS-2202, and GDS-2204), GDS-1000 series, GDS-1000A series, GDS-8x0 series, and Voltcraft-plus DSO-4000 and DSO-8000 series DSOs under Linux. The heart is a set of bash shell functions effectively turning a bash shell into a shell for communicating with the oscilloscope and for scripting measurements tasks. 170+ oscilloscope commands are modeled as bash functions. On top of these, additional functions are provided for common high-level tasks like obtaining waveform data as images. Further, GNU octave functions are provided.
