The CCD has two functional output amplifiers, 'A' and 'B'. These can be selected individually or used simultaneously. Default is 'A' only. Before using both amplifiers simultaneously, one should consider the consequences of cross-talk and a more complicated reduction due to different gain and bias behavior.
The parallel phases can be operated in ``normal'' or ``mpp'' mode. Default is mpp, where dark current is minimized.
Operating temperature is normally -100^\;
C, and testing has only been
performed at this temperature.
Two ADU conversion factors can be selected, ``high'' or ``low''. ``high'' gain is default and offers the best signal to noise ratio at the expense of a slightly reduced dynamic range.
The area to be read out may be specified by any rectangular section, and on-chip pixel binning may be specified independently in the x and y directions.
While three types of overscan can be selected, only one of them is reliable. Size is programmable, but it is required that the read-out window extends to one edge of the CCD.
