CAMAC Progress Report

                     Week Ending: October 12, 2001
                               Week: 37


Tom Folkers:
     1. Spent most of week on SMTO and 12 Meter personnel and 
        administrative issues.

Tom Sargent:
     1. Settled on a new acquisition algorithm for servo.c and wrote 
        it and began debugging.  It should be able to decelerate from 
        slew speed to essentially 0 or a bit more than tracking speed 
        at a point within a few arcminutes of the target.  Recorded 
        position data shows that the telescope is well behaved with 
        accelerations of 0.1 deg/sec. or less (actual velocity lags 
        commanded velocity by only 80ms), so this should be 
        repeatable.
     2. We noticed that the Azimuth encoder data recorded on our last 
        run at the telescope was saturating briefly at the maxima and 
        minima of the sine/cosine signals.  So, I added error checking 
        to the DSP software to have it constantly check the digitized 
        signals from the encoders to see if they are reasonable. It 
        reports errors if it sees the A/D saturate or if the maxima of 
        the sine/cosine waves is less than half of full scale. 

Pete Hubbard:
     1. On Vacation All Week.

Dave Ashby:
     1. No Report.
