                         FEC Tester Prototype


           Subcards of tester are tested individually

           Final test of complete system pending: delay due to inadvertant
           connection to power with reversed polarity.

           Still missing: bar code reader: in the process of beeing purchased

           question: at the test points only one voltage accessible
           Is it sufficient to read out the other voltages via the DCS features
           of the FEC? Otherwise we need an additional needle tester.

                          Burn in Tester



roblem: mechanics gets very elaborate with 20 – 30 cards to connect
> size problem



roposal: get away from burnin test under power
> do only passive burnin before cards are tested.

                         Readout: RCU II
e problem solved with firmware: program for flash PROM (permanent
mory) was different from version used for non permanent storage (loaded v
AG connection and “Jamplayer”/”Byteblaster” software).

e RCU II had problem with a trigger signal not beeing there.
e daughtercard had contact problems. More daughter cards are available fro
rgen/Oslo.

r the time beeing there are 4 RCUII + 1 spare for GSI/Da/FRA foreseen
ore motherboards would be helpful but not available)

 ser part of the tester at the moment operated with LabView under WINDOW
s to be migrated to LINUX since driver for RCU II readout exists only unde
NUX. It was a bit tedious to install the software for the control of the Natl.
 tr. Card which controls the pulser part of the tester (open source software, n
ectly supported by LabView).
>still not finally tested.

   Conclusions
         Progressing well

         test software still needs attention

         should be ready for larger scale test in ~ December
