   Nope, X/Y.

   To illustrate, I fired it up a moment ago to take some pics.  Here is 
my HP 54111D digital oscilloscope looking at a QYXie's infrared 
transmitter's carrier generator waveform, which is subsequently plotted 
on my HP 7550A plotter:


   The same thing could be done with a raster device (indeed the scope 
can drive an inkjet printer, which I have) but the nice color plotted 
output (being vector data to start with) looks MUCH better than a 
rasterized version.
