EVLA Monitor and Control

Monitor & Control Transition



2

Antennas

• Antennas – Front Ends Not all Front Ends Will Be EVLA Until 2010

F320 FE Transition Module Interfaces up to Two F14’s

Uses A/D Design by George Peck In-House Design Simulates VLA Dataset



3

Antennas

• Antennas – Wye Monitor System M302 Utility Interface Replacement Wye-Com Cable Will Disappear

Reduce Two M&C Systems into One Consolidate Functions to Their Devices Reduce Number of External Functions



4

Antennas

• Antennas – ACU and FRM Systems ACU & FRM System Replacements Not Part of EVLA Phase I

Bob Broilo Designed Interface Interface is Between MIB and DCS System ACU & FRM if Replaced Early Will be Paid by Operations or EVLA Contingency



5

Control Building

• Control Building To AntennasEVLA Antennas Connect to EVLA M&C

Includes Transition Modules SLC Operates VLA Antennas

Operates EVLA at VLA Baseband Until New Correlator is Installed

No VLA Baseband Transition for theNew Correlator



6

Control Building

• Control Building to Master Rack EVLA Master Rack Connected to EVLA M&C SLC Controls VLA Master Rack SLC is Connected to Modcomps

Upon Modcomp Retirement SLC will bePlaced under Control of EVLA M&C
