Hi Mark, all,

I've been thinking a bit about the relationship between the acquireTime and acquirePeriod parameters in areaDetector.

In some circumstances, scientists don't want any delay between frames, i.e. they want the acquirePeriod to be equal (or as close as possible) to the acquireTime.  They set this up for a given desired acquireTime, but are then sometimes caught out when they decrease the acquireTime but forget to decrease the acquirePeriod as well, so the overall frame rate is not what they expect.

I was wondering if people have a general way of dealing with this?  One possible solution would be to have an additional parameter to effectively disable the acquirePeriod, by forcing it to always be the minimum allowable value depending on the requirements of the particular detector and the current acquisition settings.  It would be nice to have a common solution across drivers/detectors if possible.

Cheers,
Emma
