Memory depth Each channel is associated to a 256Kbyte memory, giving a 655.36 micro-second memory depth. Should be divided in at least 2 pages. Dead time Zero dead time for page switching. Zero dead time for readout as long as the readout can sustain the data flow imposed by the trigger rate.
Digitization continues during the readout, thanks to the use of dual port memory.
Boards synchronization A common clock may be distributed to several boards through a front pannel connector. The trigger received by the board is phased with the clock and sent out through the front pannel to allow triggering other boards exactly on the same clock edge. These are made available to the readout with other logs associated to each page. Trigger logging For each trigger, the board logs the ending address of the page, a bit indicating wether the page has been totally written, and a 16bit input pattern sampled at the trigger time.
