PhotonicScienceCamera¶
In addition to expected parameters offered by the GenicamCamera class, PhotonicScienceCamera features a few more.
PhotonicScienceCamera expected parameters¶
The main parameters available for the PhotonicScienceCamera are
- X Offset [pixel]: the X offset (left offset) for the area of interest.
- Y Offset [pixel]: the Y offset (top offset) for the area of interest.
- X Binning [pixel]: the number of horizontal photo-sensitive cells that must be combined (added) together.
- Y Binning [pixel]: the number of vertical photo-sensitive cells that must be combined (added) together.
- Raw Exposure Time: the exposure time in device-specific unit.
- Trigger Mode: trigger mode selector, e.g. “freerun”, “Hardware_rising_edge”.
- Pixel Format: the format of the pixel to use during the acquisition, e.g. “Mono8”, “Mono16”.
- Sensor Width [pixel], read-only: the effective width of the sensor.
- Sensor Height [pixel], read-only: the effective height of the sensor.
- Max Width [pixel], read-only: maximum width of the image after binning, decimation or any other function changing the horizontal dimensions.
- Max Height [pixel], read-only: maximum height of the image after binning, decimation or any other function changing the vertical dimensions.
More expert-level parameters are available, and should normally not differ from the default set on the device class.
Troubleshooting¶
The camera goes regularly to UNKNOWN state¶
A known issue for Photonic Science cameras connected to the XFEL network, is that at regular time every day (ca 9 AM, 12 PM, 15 PM, …) they loose network connection. The reason could not be understood yet. The only know way to recover is by a camera power cycle (see the general Troubleshooting Section too).
When possible, it should considered the option of connection the camera to the control server directly, or via a switch, but without connecting it the the XFEL network. This configuration has proven to be unaffected by the disconnection issue.
