Question: we build our own custom frame grabbers for cameras for some custom timestamping.  is it possible to trigger the camera over CXP as described here? https://documentation.euresys.com/Products/Coaxlink/Coaxlink_10_3/Content/03_Using_Coaxlink/functional-guide/coaxpress-host-interface/cxp-trigger-control.htm

Answer: yes it is possible to do that, you just have to make sure the Frame Grabber I/O will accommodate the trigger signal, we do send trigger signal via a host often in time, see attached sample

Question: I’m trying to understand if light coming immediately after the “low time of the input pulse” affects the image being read out or goes into the next image (I think this time period might be what you call the “frame overhead time at the end of each exposure” above). If I’m still being unclear (or if I’m not understanding well enough) could we talk on the phone?  Past a certain point email can be inefficient for these more complex questions.

Answer:  I understand what you are saying, those “Frame Over head time” aka “Straddle time + dead time” are the time the camera needs to reset/send out image before the next acquisition. Sensor will not be exposed for the next acquisition before those criteria met. See attached.

Question: To make sure I’m 100% clear: any light that hits the camera in the straddletime+deadtime will be “thrown away” and not show up in any images?

Answer: Yes that is correct!
