How to reset operator ModuleCount back to 0 without stopping the acquisition.

Dear sir

We have case is need to do more FFC on a sample .

but some time will need special work.

normal work(FFC sequence): 0 1 2 3 4 5 6 7 1 2 3 . . .

special work(FFC sequence): 0 1 2 3 4 5 0 1 2 3 4 5 6 7 . . .

But we don't want frame grabber to stop acquisition .

thanks!

Hi Johannes

thank your reply.

Do you want to reset ModuloCount to 0 using a sofware reset parameter? How can you guarantee that you do the reset exactly between two images?

Yes.We hope cycle number can be reset to 0 by software(when without stopping the acquisition)

this is customer's request , they can know when is end timing of scan a sample,

so, they have some time to do something before next sample start scan.

Or do you simply need a special sequence which you can define before starting the acquisition?

Are you mean like below figure? , i think this may solve the customer's problem. thanks!

because a sample need scan 12 times , but original design maximum is 8 ffc data per cycle .

so , original sequence will like below

acquire:1 2 3 4 5 6 7 8 9 10 11 12

FFC data:1 2 3 4 5 6 7 8 1 2 3 4

so , next sample will from FFC data 5 to start.

for you reference.
