Oscopy is an interactive oscilloscope written in python designed to simplify the electrical design workflow. It allow to read, view and post-process signals with support for automatic dependency tracking.
File re-reading (updates) can be triggered by external applications like gEDA suite through D-Bus messaging system, and then Oscopy can call netlist generator and electrical simulator programs automatically.

As oscopy is built on top of IPython, post-processing include as well as simple arithmetic operations as complex functions like FFT. Oscopy can be easily extended to a multi-purpose viewer, as adding new data file formats and new types of plots is really easy.

Note: oscopy executable is called ioscopy to show it is built on top of IPython, and to prepare the separation between the framework (which manages Signals, Figures and Graphs) and the application (which manages the user interface).

• Post-processing: math expressions (through numpy ufuncs, numpy.fft)
• View, examine: multiple windows, cursors
• Data import: gnucap
• Data export: gnucap, pictures
• Dependency tracking during file updates
• Scripting
• D-Bus support: update recursively Signals by sending events from external program (e.g. gschem)
• Run netlister and simulator from oscopy
• Integration with gschem

Support for mathematic with signals is implemented. Supported functions:
numpy.ufuncs and numpy.fft

In each Graph, horizontal and vertical cursors can be toggled by using keys '1', '2', '3' and '4'.

You can drag'n drop signals from the signal list window to each graphs.
