[Vetroc_daq_sbs] ADC gate-signal

[Scott Barcus]

The instruction sheet is on the GRINCH wiki page under DAQ section
'Instructions for Running the DAQ'.
http://wm-jlab.physics.wm.edu/mediawiki/index.php/Bigbite_Gas_Cherenkov. I
don't think there is a hard copy there. If you don't have internet access
let me know and I'll find and send the PDF.
