Triggering and timings Value changes by features interdependencies The conversion between time and clock cycles affects control values. Features for pixel format, bandwidth, ROI, exposure time, and triggering are related to each other. Changing values for one feature can change values for another feature.

Page 89: Optimizing Performance
Performance and troubleshooting Optimizing performance Frame rate jitter Affected model: Alvium 1800 U-120 and U-500 Generally, some parameters can be changed during exposure without affecting the timing. When the camera is operated in freerun mode without triggering, changing parameters during exposure leads to a frame rate jitter. When parameters are entered, the next frame starts only after readout and sensor reconfiguration delay are finished. -
Page 90: Dark Current Compensation
Performance and troubleshooting Dark current compensation All sensors accumulate dark current in the pixels. Dark current increases the signal level and black level. Most sensors in Alvium USB cameras compensate for this. For Alvium 1800 U-050 with PYTHON 480 sensor, see Black level compensation for certain sensors on page 91. - Page 91 Performance and troubleshooting Additional compensation If compensation limits are reached and you cannot decrease operating temperature or exposure time, what can you do to keep signal quality high? Measures for type 1 compensation Typically, there is no measure to improve the image signal. The rising black level shifts black and dark gray values to gray.

Page 92: Operating Systems And Bandwidth
Performance and troubleshooting Operating systems and bandwidth If the camera data output exceeds the bandwidth supported by the host computer, images may be corrupted. This section gives some background information to enable proper image transfer. Sensor data output and camera data output For cameras with an image buffer, the required bandwidth for image acquisition can be estimated for a given frame rate, pixel format, and resolution by over-the thumb calculations. - Page 93 Suitable USB 3.0 accessories www.alliedvision.com/en/products/accessories for suitable USB 3.0 or 3.1 Gen 1 host controller cards and cables or contact your Allied Vision Sales representative. Vimba settings During freerun, Alvium cameras do not automatically adapt the frame rate to the USB controller's limits.

Performance and troubleshooting Dividing bandwidth between devices on a common USB 3.0 or 3.1 Gen 1 bus Ideal setup for two cameras Preconditions • Control traffic is ignored. • The possibility of the host being busy with other tasks is ignored. •... - Page 97 Performance and troubleshooting Cascading hubs divide bandwidth The following example applies to standard behavior without individual settings. The graphics show bandwidth distribution on a common bus. Three cameras try to use full bandwidth at the same time. If one camera is inactive, the host will provide its share to the others until this camera sends data again.

Performance and troubleshooting Troubleshooting common issues This section is about unexpected events with the operation of Alvium USB cameras. The events are ordered from general to detail: • Camera recognition • Unexpected events • Performance • Radio signal interference Each entry consists of: •... - Page 99 Performance and troubleshooting The camera, connected to a USB 3.0 or 3.1 Gen 1 hub, is not recognized anymore. Check if the USB 3.0 or 3.1 Gen 1 hub has crashed. Disconnect the USB and power supply cable from the hub. Reconnect both.

Page 100: Unexpected Events
The camera is intact, but your previous computer or cable has a defect. Continue with 2. The camera does not work properly. Then: Most likely, the camera has a defect. Please contact Allied Vision support. Connect the camera with the previous cable to the different computer. The camera works properly. Then: Replace the cable. -

Performance and troubleshooting Performance How can I improve camera performance? Check if the hardware sufficiently supports your USB camera. See the Alvium USB Cameras Accessory Guide at www.alliedvision.com/en/support/technical-documentation/ alvium-usb-documentation under Additional documents. Check if the camera shares the bus with other devices reducing the available bandwidth. -
Page 102: Radio Signal Interference
Performance and troubleshooting Radio signal interference How can I avoid radio signal interference from wireless devices? Ensure camera installation complies with Electromagnetic Compatibility. Wireless devices and USB 3.0 or 3.1 Gen 1 commonly use 2.4 GHz frequency (WLAN uses 2.4, 3.6, and 4.9 GHz). Even USB 3.0 and 3.1 Gen 1 cables can interfere harmfully with other electromagnetic devices. -
