[evlatests] 3bit test results

[Rick Perley]

    We ran a full bandwidth 3-bit test yesterday -- 8 GHz BW at K-band. 

    The wrong OPT was used, and the wrong m2s conversion was run on the 
file -- so the results are probably not worthy of any deep thought.  
Certainly the level setting and slope equalization did not operate. 
    But a number of antenna-IFs gave bad results, as noted in their BP 
solutions.  These (I expect) are independent of the errors listed above, 
so I list these below:

    ea02A1 -- looks like sampler or DTS
    ea10 A2C2
    ea13 A2C2 (looks like a huge delay)
    ea15 B2D2
    ea24 A2C2.  B2 had near zero amplitude.
    ea25 C1
    ea28 B2D2.
