Hardware and bandwidth
For a smooth data transfer of Alvium G1 cameras, the host computer must be
equipped with a high-bandwidth 1000BASE-T compliant NIC. We recommend
using direct point-to-point links from camera to NIC for best performance.
Vimba X settings
During freerun, Alvium G1 cameras do not automatically adapt the frame rate to
the limits of your system, including the NIC. If the data rate is too high, it receives
corrupted frames. The image transfer status in Vimba X Viewer is signaled as
Running. However, the corrupted frames are not displayed. For a solution, see
Camera cannot acquire images on page 235.
Reference system
We have tested available frame rates on a desktop PC. Cameras were operated in
AquisitionMode = Continuous, frame rates were measured using Raspberry Pi
and pigpio library.
Stated values were measured for bandwidths of 122 MByte/s and 12 MByte/s for
Operation for maximum frame rates, using the following test setup:
