My RF gear makes a plausible "vector oscilloscope" (my waveforms that
are centered around a carrier get downconverted to vector baseband),
although I haven't worked on a spiffy or flexible user interface.
Multiple 3-D wire-frame traces of ~1000 points updating faster than
the eye can follow, on crappy old Intel laptop graphics chips.
I use fltk+opengl, based on the fltk cubeview demo code, processing
data brought in over USB at typically 8 Mbyte/sec.
