Ah ok i think i'm starting to understand. So I can't really do anything with the sweep option :P
When i press it, i see that it draws one sweep but it then dissapears immediatly, and on a high freq thats instantaneous. But thanks for all the replies! :P

Yes, this is exactly what single is for, not very useful nowadays. Where would you develop the film?  :-\
I suppose if it had outputs on the back you might be able to capture and store the waveform, or otherwise play with it, one sweep at a time. I'm not sure if it's within the capability of this scope however.

Many digital cameras have exposure times long enough to be useable with a single-sweep mode like this if you're really keen to experiment...

Simon:
true, any SLY will have a remote jack that will fire the shutter so you can easily wire it to the scope

Only ever seen an oscilloscope camera but not used one.It fixed to the bezel of the scope and set with the shutter open permanently, but as the mounting was light tight this was ok.The scope was then set to trigger on a non repetitive event in single sweep mode.When the scope triggered the trace was captured on the film.Normally a polaroid type camera, the exposed image could the be developed and viewed, the test repeated if required. With digital scopes this has become mainly obsolete but is still the only way to capture a trace on most analogue scopes.
