1. MBT Alpha SFOSLIC SFOCIC Front Ends L1 (SCL) MBT Alpha SLIC Example: Test Stand Shadowing a SLIC Test Stand A.Maciel L2mu NIU Target Shadow MBT/Alpha outputs not shown coaxialUTP undo (*) Need SFO at receiving end because SLICs are not transformer coupled, and therefore should not be plugged to long cables. You also want to send single channels only to test stand. SFO pigtail

2. SFO Usage as Central Scint.

7. Shadowing a Generic SLIC A.Maciel L2mu NIU Generic SLIC has 8 double channel inputs; (SCL,idle) (ch.2, ch.3) (ch.14,ch.15) one single seven doubles Step 1; convert double inputs to 14 singles. 7(1  2) pigtails Step 2; make 14 data copies 6x(1  2) = 1 st dedicated SFO 6x(1  2) = 2 nd dedicated SFO 2x(1  2) = borrowed SFO Step 3; connect 14 channels PP MCH2  PP FCH2 PP has chs.215 specified Step 4; convert 14 single inputs to 7 doubles [7(2  1) pigtails] acc. to specific SLIC under study, re-connect target SLIC Step 5; repeat step 4 at Test Stand, connect shadow SLIC. 7(1  2) pigtails Step 6;
