DC power

• SLAC to ship 16 gauge single pair cable connectors and pins to ATF

• Cable installation. (ATF)– Make all lengths the same. – Connect drain wire to return DIN rail in rack– Connect drain wire to spade lug on tunnel end

for possible connection to downmix box.

• Build 15V 5amp LO amp power supply chassis (ATF/SLAC)

Put a connector on the drain wire as shown for grounding the connector shell if needed

DC Power Distribution

Attach drain wire with DC return wire to return blocks

IF Cables

LO/CAL Cable Installation• Install cable as shown in the following sketches.

– Install Male type N connectors on ½” and 3/8” heliax.

(ATF)

– Keep cable paths as short as possible. Mount couplers and splitters securely, and out of foot traffic. Attach 3/8” cable to the downmix box

standoffs as shown. (ATF)– SLAC to provide LO tunnel amp

and splitter

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.
