[evlatests] Switched power stability at C-band

[Rick Perley]

    I have reviewed the switched power data at C-band taken in the same 
run as the X-band data that I summarized a few moments ago. 
    At C-band we have an *entirely* different picture.  Nearly all the 
antennas provide smooth and stable PDif.  Virtually no IFs had drops, 
spins, or irregularities, other than the 'non-linearity' that I have 
already reported on a couple weeks ago.  (To remind, this is the 
curiosity that the PDif changes amplitude when  on sources of different 
amplitude, presumably due to a non-linearity in the gain response). 
    This striking difference between C and X bands illustrates the 
difficulty in finding repeatable 'bad behaviors'...
