M. Noy 29-01-2003 Results from the system: preliminary
M. Noy 29-01-2003 The optical output is fed into the first Optobahn opto-rx version, through 50 co-ax, into a 50 terminated scope. Analogue square wave, period 50ns. (channel 0, bias setting 0x17, gain setting 1) 10% to 90% rise time: 3.60.2 ns 90% to 10% fall time: 3.40.2 ns Settling time believed to be better than 17ns, analogue noise believed to be less than 10mV, but not characterised yet.
M. Noy 29-01-2003 Linearity looks sufficient, but no detailed measurements have been made yet.

M. Noy 29-01-2003 Summary The optical test board works, and will be used to test the FF1. Have a 9U crate, VME64x backplane, and 3.3v psu at IC. Software for the set up is functional, we can produce test vectors and sequence tests. Some work is required to make it more user-friendly. The next optical test card is being developed to provide multiple individually configurable channels, stepping towards more automation ( production testing)
