v4 v5 9 9 == Djitter Clock == 10 10 Incoming clock signal taken at the input of the LVDS/unipolar convertor of the board (polarity minus) 11 11 12 [[Image(clock2.bmp)]] 13 12 14 Clock signal taken at the output of the click buffer driver. 15 13 16 [[Image(clock3.bmp)]] 17 14 18 Clock signal taken at the output of the Delay chip for ADC 0. 19 15 20 [[Image(clock4.bmp)]] 21 16 22 Clock ADC 0 (polarity +). 23 17 24 [[Image(clock5.bmp)]] 25 18 26 Clock ADC 0 (polarity -). 27 19 28 [[Image(clock6.bmp)]] 29 20 30 21 31 == Djitter L0 == 22 32 L0 signal at the output of the LVDS/unipolar convertor of the FEB. 33 23 34 [[Image(L0_1.bmp)]] 35 24 36 L0 signal at the output of the Sequencer 37 25 38 [[Image(L0_2.bmp)]] 26 39 40 41 27 42 == Djitter Read Command == 28 First RdCmd at the output of the Sequencer. The First rrdCmd is uned as the scope trigger. Large djitter wrt to the CROC clock. 43 44 First RdCmd at the output of the Sequencer. The First rrdCmd is uned as the scope trigger. Large djitter wrt 45 to the CROC clock. 46 29 47 [[Image(rd_1.bmp)]] 30 One of the next RdCmd (8?). We have both a djitter wrt the clock (green) but also wrt the first RdCmd still used as the trigger reference. 48 49 One of the next RdCmd (8?). We have both a djitter wrt the clock (green) but also wrt the first RdCmd still 50 used as the trigger reference. 51 31 52 [[Image(rd_2.bmp)]] 32 53 54
