Hardware Checkout DC power –Confirm voltage at the downmix box is between 8 and 9V. (SLAC) LO Power –Set Locking Box output power so that there is -10dbm at the input to high power amp in the tunnel. (SLAC) –Set power level at the downmix box end of the 3/8” cable, to between 3 to 4dbm. (SLAC)

Hardware Checkout (cont) –Adjust all LO phases to be the same for single pulse operation. (SLAC with ATF help) CAL Power –Use RF source to produce CAL tone and inject it into CAL cable system. Adjust CAL tone power level at downmix boxes to be about -10dbm. (SLAC) –Design CAL tone generator locked to 714MHz (SLAC)

Software Work Software work to be done. –Load CPU operating system VXWorks/Artems digitizer software etc….. –Before beam stop in May of 08, use Test Bed QBPM with nanobpm VME crate, CPU and digitizers to: Test Matlab code for single pulse calibration data acquisition. Test DDC library codes for QBPM data acquisition. Create EPICS panels to interface with data taking software Write analog digitization software for monitoring LO levels, downmix box temperatures, etc. Write CAL tone digitization software to track system gains for each channel Work to be done by SLAC and RH personnel. Software is THE critical path item for successful QBPM operation in October.
