1 QBPM System Installation Systems –Rack mount chassis –LO and CAL RF cable plant ( need 714Mhz from eels bedroom) –Down mix boxes –DC power cable plant –IF signal cable plant –Analog read back cable plant –SIS Signal assignments

2 DC power distribution DC power supply BPM signal patch panel VME crate Analog signal interface Cable Feed through RF amplifier pwr supply Cal Tone Generator Cable Feed through SLAC supplied Cable Feed through 6446 MHz LO Locking box QBPM Rack Layout 40 Rack units required Existing unit 5 Units 2 Units 4 Units 2 Units 3 Units 9 Units 2 Units 4 Units 1 Unit Still to be designed Need 15V at 5 amps Could use existing Nanobpm VME crate but should buy a new VME 64x crate Also need a new CPU

3 LO power budget/ cable plant 33 dbm max amp output 29.5dbm after splitter 7m of LDF4-50 cable = 1.4 db plus 0.25 db per connector=1.9db loss 27.6dbm 26.88dbm 13.5m of LDF4-50 cable = 2.71 db plus 0.25 db per connector=3.25db loss 23.63dbm 20.13dbm after splitter 20m of LDF4-50 cable = 4 db plus 0.25 db per connector=4.5db loss 15.63 dbm 1db loss in these cables 17.6dbm 26.88dbm 16.6dbm 27.6dbm 16.6dbm 10m of LDF4-50 cable = 2db plus 0.25 db per connector=2.5db loss 24.3dbm All 8 way splitters have 10db loss All cables from 8 way to down mix boxes should have no more than 2db loss These cables should be made from LDF2-50 0.32db/meter

4 Some where in this location is an ideal location for QBPM electronics 42 db gain 33dbm amp with 2way splitter 8 way splitters 10db directional couplers 2 way 3 db splitter LDF4-50 cable or equivalent LDF2-50 cable

5 8 way splitter LDF4-50 cable or equivalent 6 way splitter LDF2-50 cable

6 8 way splitters LDF4-50 cable or equivalent LDF2-50 cable Some where in this location is an ideal location for QBPM electronics

7 Downmix boxes Downmix boxes and hybrids to be mounted on to the steel plate fixed to the side of the concrete magnet supports Downmix boxes to be on 25mm standoffs (SLAC supplied) Hybrid Downmix box standoffs

8 Put a connector on the drain wire as shown for grounding the connector shell if needed DC Power Distribution

13 Parts to buy to complete RF BPM system RF BPM LO and CAL cable plant –500 ft of Andrews LDF4-50 or equivalent LO from source to splitters. With a loss/meter at 6400MHz of 6.5 db/30m. 44 L4NM-C type N male connectors for both ends. Flare tool Andrews part# 224363 Cable preparation tool Andrews part# MCPT-L4 –1000 ft of Andrews LDF2-50 or equivalent for LO from splitters to electronics. With a loss/meter at 6400MHz of 10.2 db/30m. 156 L2PNM-HC type N male connectors. – Two 2 way 3db splitters that will work at 33dbm power levels. Pulsar Microwave PS2-13-450/3N or equivalent –Two 6 way splitters with Type N female connectors. Pulsar Microwave PS6-06-434/1N or equivalent –Conformal cable and connectors for LO and CAL jumpers.
