Dear Imcalers:

The System PDR and the Test Interferometer PDR are next week.  Please review
the materials and give comments to Jeff Mangum or to me.

Larry's list of readings:
RECOMMENDED READING LIST

ALMA SYSTEM DESIGN PDR 

Requirements and Standards

  http://www.tuc.nrao.edu/~ldaddari/rcvrSpecs.txt
  http://www.tuc.nrao.edu/~ldaddari/loSpec.txt
  http://www.tuc.nrao.edu/~ldaddari/phaseSpecs.txt

Block Diagram and Baseline Design

  http://www.tuc.nrao.edu/~ldaddari/alma.pdf	;block diagram, 10p.
  (Note that pages 1-7 are B size and are not very readable if reduced
  to A or A4.  Pages 8-10 are A size.)

  http://www.tuc.nrao.edu/~ldaddari/loPlan.txt
  This file should be on hand when studying the LO parts of the block
  diagram.  It explains the frequency conversion scheme for each band.

Major Design Decisions Taken

  http://www.tuc.nrao.edu/~ldaddari/ifband.txt
  Memo summarizing discussions of choice of 4-12 GHz for the 1st IF,
  with copies of all relevant email attached.

  http://www.tuc.nrao.edu/~ldaddari/loBaseline.txt
  Pros and cons of various LO options considered, with the reasons
  that the present baseline ("millimeter wavelength reference" option)
  was chosen.

Alternative Designs -- different IF and baseband bandwidths

  http://www.tuc.nrao.edu/~ldaddari/bandwidthIdea.txt
  
Timing and Synchronization

  http://www.tuc.nrao.edu/~ldaddari/timing.txt

Fringe Rotation, Phase Switching and Related Issues

  http://www.tuc.nrao.edu/~ldaddari/memo287.pdf
  Advance copy of ALMA memo, in distribution this week.

Power Distributon

TEST INTERFEROMETER CDR

All material is still in the Test Interferometer Project Book, which
continues to get minor updates:
