Status• All boards are designed for the FEM system except for

the test pulse board.– Only the optical out need to be checked before fabrication

• Testing procedure– Clock master need to be tested first

• System download • Serial read-back• Clocks

– Clock fanout board next – Backplane +ADC – We now have a standalone system– Need optical board -> New DCM daughter card

• New DCM daughter card will be designed soon.

• Good news– We finally get HBD money

• Now we can fabricate these boards and buy the parts

Need to work out soon

• What items need to be purchased now for the data taking (long lead time items)– Power supply– Signal cables (how many we need ?)– Clock cables– What is the minimal channels need to be

instrumented?• how many ADC boards needed to built?• We don’t have production money

– Normally this fund is released after prototype and final design review.
