AW00011916000 Network Related Camera Parameters and Managing Bandwidth
Basler scout GigE 61
(6) You trigger image acquisition and during this time period, the camera acquires and transmits
a frame. The bandwidth reserve setting would allow 5 resends during this time period and 1
resend is needed. The 1 resend needed is taken from the resends available via the
bandwidth reserve. The other 4 resends available via the bandwidth reserve are not needed,
so they are added to the accumulator pool and they bring the pool up to 4.
(7) During this time period, you do not trigger image acquisition. You delay triggering acquisition
for the period of time that would normally be needed to acquire and transmit a single image.
The current camera settings would allow 5 resends to occur during this period of time. But
since no data is transmitted, no resends are required. The 5 resends that could have
occurred are added to the accumulator pool and they bring the pool up to 9.
(8) You trigger image acquisition and during this time period, the camera acquires and transmits
a frame. The bandwidth reserve setting would allow 5 resends during this time period, but no
resends are needed. The 5 resends available via the bandwidth reserve are not needed, so
they are added to the accumulator pool and they bring the pool up to 14.
(9) You trigger image acquisition and during this time period, the camera acquires and transmits
a frame. The bandwidth reserve setting would allow 5 resends during this time period and 1
resend is needed. The 1 resend needed is taken from the resends available via the
bandwidth reserve. The other 4 resends available via the bandwidth reserve are not needed,
so they are added to the accumulator pool. Note that with the current settings, the
accumulator pool can only hold a maximum of 15 resends. So the pool is now 15.
Frame Max Jitter (read only)
If the Bandwidth Reserve Accumulation parameter is set to a high value, the camera can
experience a large burst of data resends during transmission of a frame. This burst of resends will
delay the start of transmission of the next acquired frame. The Frame Max Jitter parameter
indicates the maximum time in ticks (one tick = 8 ns) that the next frame transmission could be
delayed due to a burst of resends.
Device Max Throughput (read only)
Indicates the maximum amount of data (in bytes per second) that the camera could generate given
its current settings and an ideal world. This parameter gives no regard to whether the GigE network
has the capacity to carry all of the data and does not consider any bandwidth required for resends.
In essence, this parameter indicates the maximum amount of data the camera could generate with
no network restrictions.
If the Acquisition Frame Rate abs parameter has been used to set the camera’s frame rate, the
camera will use this frame rate setting to calculate the device max throughput. If software or
hardware triggering is being used to control the camera’s frame rate, the maximum frame rate
allowed with the current camera settings will be used to calculate the device max throughput.
