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?
