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

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)

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.

Installation Plan

• Install equipment in the rack• Pull in:

• LO and CAL cables (still to be purchased)• DC power cables ( now at SLAC)• Analog signal cables (still to be purchased)• IF signal cables ( now at SLAC)

• Adjust LO phases for single pulse calibration

operation.• Test data acquisition software.
