Because I like Tkinter more than wxPython I am playing with the Widget Construction Kit (http://effbot.org/zone/wck.htm). I attach the code for an oscilloscope and spectrum analyzer. I am also working on a network analzyer but it is not usable yet. Using: UP and DOWN keys change y scale SHIFT-UP and -DOWN move y position LEFT and RIGHT keys change time scale TAB switches to next channel SHIFT-TAB to last q for quit. I won't bet it's faster than wxPython. Need to test it. Maybe a block gr.dB would could improve the speed? Thomas
