    keyword=cavity 2 checkout

    Here are runs to checkout cavity 2 with spectr. DAQ. The HAPPEX
    DAQ was run also, but I don't have that info (separate halog).
    Notation: cavity 2 is ~10 m from target, cavity 3 is ~2m.
    (and cavity 1 is in BSY).

    
Gain adjustment tests
    
First adjusting on cav2.
    

    
run 2017
    
Nominal setting
    
q2 = 1677
    
x2 = 8000
    
x3 = 8000
    

    
run 2018
    
q2 -> 12400  (others same)

The phase on x2 was, up to now, -32767
    
Put x2 phase to +32767
    
Everything else stays the same
