[Amanda Hoebel]

Dear Dr. Sandorfi,

Attached find DSG's response to the Status document. I have also attached the CT-Box users manual which contains the specifications.

Regards,
Amanda

Dear Amanda,

The attached file contains three sections. (We've highlighted a few specific
places where we would appreciate feedback.)
 
(I) a summary of Xiangdong's main points from Dec 5/16. As we send such
notes back and forth, it would be helpful to "check off" the points when
completed, and note the extent of the testing.

(II) the required range of the user-defined parameters that are loaded into
the setup table for the NMRS program.

(III) a discussion of our synchronization requirements, with questions as to
what options you are pursuing.

Thank you,
Andy Sandorfi and Xiangdong Wei

Thank you for your email. With regards to the 3 items

The following have been completed for Rack 2

   1. Updated FRS and NMR programs to LabVIEW 2015.
   2. Added

   3. Replaced old cables with new low-noise cables.

   5. Modified NMR program

   6. Added Tbottom and Twait

   7. Made Tup and Tdown independent of each other (for

We need to know what else needs to be focused on in order to

For the synchronization of

Please provide us with this information and we will
