    Had MCC put FFB into "manual gain mode" and do a manual gain search
    at 36 uA.  This keeps FFB from regaining during the test.
    
    Hall C kindly turned off for us to do this test, so we shouldn't 
    have to worry about bleedthrough for the Unser pedestal.
    
    I kept the Unser in low gain because I decided that I liked the fact that the 
    pedestal is at 3k channels (instead of 1k) and the noise isn't better at higher 
    gain, as its dominated by detector noise (which amplifies at higher gain) 
    rather than by ADC electronics noise.
    
    Run 3158  - Checking parameters on current lock.  
    	settled on interval=6 and ramp-rate = 1. 
    
    Run 3159  - About 10 scans altogether.  Should be useful for calibrating 
    pedestals for BCMs 1,2,3,7 and 8, BPMs 8, 10, 12, 4a, 4b, dets 1-4, blumi 1-8, 
    and flumi 1 & 2.
