Generalize how to set detector count time

Open prjemian opened this issue 6 years ago • 0 comments

relates to #23 and to https://github.com/NSLS-II/bluesky/issues/997

Count time is implemented differently, based on the detector type (and conceivable other hardware-specific features). Here's the ones I know about now:

  • SynSignal : bps.mv(det.exposure_time, time))
  • EpicsScaler : bps.mv(det.preset_time, time)
  • ScalerCH : bps.mv(det.preset_time, time)
  • areadetector.DetectorBase : bps.mv(det.cam.acquire_time, time)

Supporting negative time to count against a monitor detector is only supported by EpicsScaler and ScalerCH in the underlying EPICS record support. That may have to drop from this feature request.
