Pre-Acquisition Setup - CCD
5.3.2.3 - Full Vertical Binning (FVB)
FVB allows the user to operate the CCD-chip as a linear image sensor (a photodiode array), typically for spectroscopy
applications. The charges from each column of pixels (each column being the chip height) are combined, or binned,
on the chip to give one single signal value per column. FVB mode is selected in the Setup Acquisition dialog box as
shown below:
For some spectrographs, it may be necessary to change the direction in which the data is displayed on screen. This is
accessible in the setup acquisition dialogue, in the FVB tab as shown below:
In some instances spectral rate can be more important than spatial/spectral resolution. For such applications, horizontal
binning can be applied by setting the desired binning format in the Horizontal Binning section of the acquisition setup
interface (see section 5.3.3.1) to a value greater than one.
