CV-M2CL and CV-M8CL
6.2.10. Vertical binning
Note! Vertical binning is not supported from revision D!
Vertical binning is a function on CV-M2CL only. It will add the pixel value from 2 adjacent lines,
and read it out as a single line. The sensitivity is then doubled, but the vertical resolution is
reduced to ½.
The vertical binning is done by reading the charge from 2 vertical ccd cells into 1 horizontal ccd
cell. It is only done only for lines during the DVAL high period. It will not change the Horizontal
timing.
Binning is available for CV-M2CL in Normal mode (TR=0), EPS mode (TR=1) and PWC mode
(TR=2).
Binning will not work together with partial scanning. If both are set at the same time, binning
has the highest priority.
The below shown vertical timing is for normal mode (TR=0).
