[evlatests] EVLA tests of Sept 7

[Rick Perley]

    I had 2.5 hours scheduled test time last evening.  The intention was 
to do sensitivity
and stability tests of antennas 14 and 16 at L, C, X, and K bands. 

    A sign of trouble appeared just before 5PM, when it was reported by 
numerous
individuals that antenna 14 was non-responsive.   A final email from Jim 
Jackson
postulated a problem in the fiber network.

    But antenna 16 was reported as functional, with at least 2 IFs 
nominally working,
so it was decided to continue with the run. 

    No useful data from either antenna were obtained.  The operator log 
reported
that both 14 and 16 were 'in elevation limit'.  A later note recorded 
that  Tom Frost
was called out. 

    Can anybody explain how a perfectly good Observe file can drive the two
EVLA antennas into their elevation limit?  (All the VLA antennas worked
normally). 

    It would be very useful to recover these two antennas, so part of 
today's
software time can be used to do these tests.
