Carioca threshold,pulse,charge dac
Signal processed from carioca(Analog) and then from dialog (digital)
I2c lvds+pulse signal
Self Test of the Carioca-Dialog system(Using Dialog & Service Board facility)
• Only one conection (i2c_lvds)• The system can test :
board connectivity,carioca channel response,dialog and Carioca functionality
• The input and spark protection are tested using rate method to measure detector’s capacitance
• The LVDS output are not tested

Cardiac Singnature
• The Cardiac board contains two Carioca• The Offset for each carioca channel is different• The 16x8bit value of the offset give a way to identify the cardiac.• We aspect: bar code-> cardiac signature is a biunivocal.

Testbench Flow• Scan Chamber Barcode• Scan Cardiacs Barcode in given order • Camera File Chamber code+cardiacs code• Testbench program associate cardiacs with production
cardiacs database.• First injection test discover any swapped ecs cable lvds
cable • Test cardiac analog injection and test pattern• Cardiac offset scan channel signature discover any
mismatch cardiac barcode geo position of any cardiac• Noise method -> chamber capacitance ->short channel
or open channel• One file for each chamber

Testbench Status• Roma1 Cardiac Test program used as skeleton and
Adapted. OK• Insert the ACQ read function in the skeleton OK• Add automatic analisys using “root” library for rate
method analisys. OK• Add new functionality for easy use 99% done • System assembled in Rome2 OK• Gateboard prototype OK• Gateboard final PCB (gerber file to pcb company 2 weeks
ready)• The first pilot use in LNF in two weeks
