(*) Need SFO at receiving end because SLICs are not transformercoupled, and therefore should not be plugged to long cables.
You also want to send single channels only to test stand.

Shadowing a Generic SLICShadowing a Generic SLIC
A.MacielL2muNIU
Generic SLIC has 8double 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(12) pigtails
• Step 2; make 14 data copies 6x(12) = 1st dedicated SFO 6x(12) = 2nd dedicated SFO 2x(12) = borrowed SFO
• Step 3; connect 14 channels PPMCH2 PPFCH2
PP has chs.2•••15 specified
• Step 4; convert 14 single inputs to 7 doubles [7(21) pigtails]
acc. to specific SLIC under study, re-connect target SLIC
• Step 5; repeat step 4 at Test Stand,connect shadow SLIC. 7(12) pigtails
• Step 6;
