Abstract : We perform a detailed characterisation of the 4K x 4K CCD camera developed for the ADFOSC backend instrument on the 3.6m DOT. The performance of the CCD is characterised in the ARIES laboratory and based on the experiments different parameters were tuned to obtain the optimum performance for both single and four-port readout modes in different gain settings. We also perform sky tests to test the optimum performance obtained in the lab. The CCD has a linear response up to saturation and has an optimum gain setting of 1. Also, the CCD camera acts as a nominal grade-0 CCD below -110 deg C. Bias level is quite stable. Dark current is negligible below 115 deg C for long integration times.
