     6In the following, the green signal is the reference CROC Global clock signal (CROC quartz), the yellow signal
     7is either the clock of the front-end board, the L0 or the read_command. Green is the trigger for the clock study, the yellow signal is the trigger when looking at the L0 and the Read Command.

     10Incoming clock signal taken at the input of the LVDS/unipolar convertor of the board (polarity minus)

     12Clock signal taken at the output of the click buffer driver.

     14Clock signal taken at the output of the Delay chip for ADC 0.
    1215[[Image(clock4.bmp)]]
    13 
     16Clock ADC 0 (polarity +).
    1417[[Image(clock5.bmp)]]
    15 
     18Clock ADC 0 (polarity -).

    1921== Djitter L0 ==

     22L0 signal at the output of the LVDS/unipolar convertor of the FEB.
     23[[Image(L0_1.bmp)]]
     24L0 signal at the output of the Sequencer
     25[[Image(L0_2.bmp)]]
    2126
    2227== Djitter Read Command ==
     28First RdCmd at the output of the Sequencer. The First rrdCmd is uned as the scope trigger. Large djitter wrt to the CROC clock.
     29[[Image(rd_1.bmp)]]
     30One 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.
