Nick DiMonte at the APS has written a nice support package for Tektronix 3000/5000 oscilloscopes.   The same driver works with Network, GPIB, or RS-232 interfaces.
I believe that the screens are still MEDM-only.

Many oscilloscopes nowadays use Windows as the operating system and come with an API to get direct access to the oscilloscope functions. This allows to write an EPICS device driver. Running the IOC directly on the oscilloscope saves some network traffic. With an external IOC, the data is first transferred from the oscilloscope to the IOC (e.g. via VXI11) and then from the IOC to the client via Channel Access. With an IOC integrated into the oscilloscope, you only have Channel Access. But writing such a driver is somewhat sophisticated.
