After launching FengYun-4(FY-4), the on-orbit test to the satellite is done, the MTF of the solar reflectance bands is better than 0.14, 0.17 and 0.22, that is better than the designed capability. The noise test is based on the black-body on the apparatus, the noise for all the infrared bands is less than 0.2 K@300 K, the noise of the best band is about 0.06 K@300 K. The calibration precession of infrared band is validated by the GSICS algorithm, the bias of all the infrared bands are less than 1K comparing to IASI, the bias of the best band is about 0.3 K@290 K. The RGB image carries more information than the gray image, although the AGRI has 6 solar reflectance bands, there are no real red, green and blue bands of human beings, a new algorithm generating RGB image for AGRI is suggested, based on the character of 0.82 band, a very beautiful RGB image which is good to human beings is generated, that improves the multi band use for AGRI.
