CAMAC Progress Report

                    Week Ending: February 22, 2002
                               Week: 56


Tom Folkers:
     1. More work on the DBE driver code.
     2. Preparing the DBE for the first tests next week.

Tom Sargent:
     1. Fixed a couple of bugs in the sun avoidance code.  I believe 
        the logic that computes the path is correct now, except for 
        the fact that the wrap hasn't yet been addressed. 
     2. Helped Pete verify that the A/D cards received back from 
        Traquair still work and appear to have the specified 1KHz 
        filters installed.
     3. Made additions to the servo code so that it can follow a path 
        described as a list of points. That is the output of the sun 
        avoidance computation.  Previously, it just took a start and 
        end point and  drove elevation and Azimuth in a decoupled 
        fashion until each independently reached the target location.  
        (that simpler method is still used when the sun is below the 
        horizon.)

Pete Hubbard:
     1. Testing the Traquair A/D boards low pass filter after 
        modification. The attenuation now starts at 1 kHz.
     2. Changed MPI 6000 amplifier boards input stage to differential 
        and used a LTC1052 chopper amp that has a 600 Hz chopping 
        frequency.
     3. Converted the MPI 6000 board that has been used for testing in 
        the lab so it will be able to be used at SMT. Had to add the 
        Rod Ref signal that is used to set telescope ref point.
     4. Tested all cards in lab telescope hardware to ready for SMT 
        testing.

Lori Warner:
     1. No Report.

Dave Ashby:
     1. No Report.
