PixelClk_Hz
The pixel clock is a signal internal to the camera, according to which pixels are sequentially extracted out of the CCD sensor.
All line-scan cameras and some area-scan cameras are equipped with a pixel clock output. In this case, the frame grabber should be able to sense the pixel clock frequency.
An analog area-scan camera synchronizing the frame grabber by means of the pixel clock is said to work in digital synchronization mode. This is reflected by the parameter SyncMode valued to DIGITAL.
When an analog area-can camera does not use the pixel clock synchronization, the frame grabber builds an internal sampling frequency, which can differ from the pixel frequency inside the camera. This internal sampling frequency is reflected by the parameter SampleClk_Hz.
