Channels Channel 20 Channel 1 3

Input for pulser Input 2 (11 -20 channels) Input 1 (1 -10 channels) Pulse applied to capacitances of 50 f. F 4

Board-FPGA connection Output connector (to be connected with the second connector on the FPGA) FPGA connector (to be connected with the first connector on the FPGA) 5

Jumper position Jumpers To keep fixed in position Jumpers Position for FPGA threshold scan (for a manual scan must be moved to the right pin). V_th can be fixed externally with a bias applied to the central pin of J 8 6

Channels termination To use the differential probe is necessary to terminate the differential output with 100 Ohm + - 100 Ohom + Using the FPGA or HPTD the 100 Ohm terminations are inside them - 7

Bias working point Preamp current TIA_bias (TP 11) > 800 m. V is the range of work DISC 1_bias (TP 14) 275 -460 m. V is the range of work DISC 2_bias (TP 15) 440 m. V is the upper limit of work DISC 1_bias and DISC 2_bias define the working range of the channels 8
