Chronos User Discussion / Is this a known issue and if so is there a workaround?
« on: November 12, 2024, 11:16:45 PM »
Hi,
We use a Chronos 1.4 (0.6 firmware) to shoot typically 50 blocks (segments) of 400 images at close to max frame rate (995fps). FWIW each segment is started at about 5 seconds interval, using an external TTL trigger on the BNC input of trigg1.
I would expect the exported images to be frame_000001.tiff->frame_000400.tiff for the first block, then 401->800 for the second block and so on. But instead the first block only has 398 images (frame_000001.tiff->frame_000398.tiff) while the second and the others (except the last) have the expected 400 images (399->798, 799...). Finally, the last block contains 403 images, the last 3 of which seem to belong to the beginning of the first block.
Is this a known issue and if so is there a workaround?
Since my explanation may be confusing, don't hesitate to ask for details.
