| - | ===== Calibrate offset ===== | + | === Calibrate offset === |
| + | |||
| + | |||
| + | dbbcif{a,b,c,d,e,f}=2,60 //- Set a strong attenuation for each of the IF// | ||
| + | dbbcif{a,b,c,d,e,f} //- Check that each TPI value is in the order between 1000 to 8000// | ||
| + | cal_offset={1,2,3,4,5,6} //- Launch the cal_offset program for each the Core boards// | ||
| + | |||
| + | One offset calibration per board, so in total it is needed to conduct the offset calibration 6 times. | ||
| + | |||
| + | === Calibrate gain === | ||
| + | |||
| + | dbbcif{a,b,c,d,e,f}=2,agc,1,34000 //- Set an intermediate TPI value (34000) and wait until value reach// | ||
| + | dbbcif{a,b,c,d,e,f}=2,man //- Set dbbcif with agc off // | ||
| + | cal_gain={1,2,3,4,5,6} //- Launch the cal_gain program for each the Core boards// | ||
| + | |||
| + | Again 6 calibrations are needed. | ||
| + | |||
| + | === Calibrate delay === | ||
| + | |||
| + | Do it after the gain and offset calibration. Use similar initial settings for each board as in the Calibration gain procedure. | ||
| + | |||
