Entry number 370522

On Tuesday Ryan and I connected the signals used to form T2 on the RHRS to a patch panel that 
comes upstairs to the counting house.   The attached scope picture shows the signals with 50nA 
of beam.  

Although its a little hard to see, the yellow signal (labeled) is the strobe.  The blue signal is the 
"or" of s1, purple is the "or" of s2m, and green is the "or" of the GC.  All of the logic signals come 
at least 25ns before the strobe, which is the appropriate timing for the trigger.
