Re: Scanning 101

[Hinko Kocevar via Tech-talk <tech-talk@aps.anl.gov>]

Pete, I will surely check out this tool, even if it goes beyond EPICS Db only approach that I mentioned before. In fact, some of the resourceful people at my facility have already started using python based tools to tackle the task of scanning on top of sscan based EPICS solution.

Thanks,
Hinko

You can assume that the (low-level) EPICS modules supporting the hardware are under my control already, I'm interested in orchestrating the scan using above constituents.
