[evlatests] Current State

[Rick Perley]

    After various resets and updates, we checked system performance. 

    For the most part, the (Modcomp-driven) system is working well. 

    IF 'D', at all bands, is giving very unstable data -- both 
amplitudes and phases are bad on all antennas (including VLA antennas), 
at all bands.   Some antennas (like 24) are especially bad. 


    Other IFs are working well. 

    Antenna 21 is dead on IFs C and D. 

    Something happened to all the EVLA antennas between 15:28:57 and 
15:29:58.  Data were bad for all of them (but not all at the same time) 
within that interval.
