Adders in drawer Test of TileCal Level 1 Interface drawer patch panel trigger cable ca 70 m receiver pre-processor TileCal patch panel RP patch panel TileCal Lvl1

The task is to test the information transfer between the TileCal adder boards and the Level 1 preprocessor. test the trigger cables the receivers the patch panel connections the pre-processor Serve as a test bench for the first level trigger. The tests should preferably also be compatible with the similar LAr tests

MobiDAQ VME test crate developed at CERN to test data from 8 drawers at a time. MobiTrig We suggest to have a standalone crate to test the trigger signals. Develop this in Stockholm. Tests should check for continuity, absence of shorts, cross talk, noise levels, pulse shapes and attenuation.

Components of MobiTrig VME-crate (borrow) VME processor, CCT (CERN pool?) ADC 8 channels, 12 or 14 bits, sampling (borrow?) MUX (to be bought) TTC receiver module Functionality TCP/IP controlled: initialize, set MUX Reports settings and data to COOL (POOL) Activated by TTC fiber, L1a
