Rough Hardware Timeline and Coordination Details

(Taken from Steve's Official KFPA Gantt Chart and meeting in Amy's office [Feb 27, 2009] - Is this Gantt chart on the wiki somewhere?)

• Parts are currently (as of Feb 27, 2009) on order for M&C cards. Building of cards should happen in April 2009 with the cards available for testing in May 2009.
• Dewar together in June 2009 and available late August 2009
• Serious testing in the lab starts in October 2009 and goes through November 2009
  • Really need a Manager at this point
  • The primary points of contact for the M&C hardware are Galen Watts and Bob Simon. Roger Norrod providing some input as well. There is a document describing detailed requirements for M&C.
  • Messaging/alarms will be similar to the existing K-band receiver. Wording of the messages needs to be coordinated with the hardware engineers and operations.
  • The hardware engineers will require a way to test/troubleshoot the KFPA using a laptop. The Manager could be used for this as was done for Mustang.
  • Will finally have access to the entire receiver as a system at this point. However, individual components will be available piece-meal before then.
• Expect to do commissioning on the GBT January 1, 2010
  • Will need fully system integration with Astrid by this point.
  • The Measurements Manager will have to accept tables of cal values from the KFPA. There will be 14 rows of cal values (2 rows/pixel).
  • A balancing capability will have to be added to the current Balancing API, which will set attenuators in the downconverter. This is a periodic balancing activity that can be done between scans.

Reference Planning Documents:

• TBD

Feature	Dependencies	Effort	Rationale	Notes	Status
Measurements Manager				Includes changes to calibration database schema. Has this been proven to work with array receivers?
IF Manager				Properly simulate IF path between receiver and backend.
LO1 Manager				LO1 entries for receiver. See Joe for how-to.
Antenna Manager				Joe will need to add this receiver to the list of available receivers.
CLEO				What needs to be done if there is no custom screen?
