Simplified schematics for the three data acquisition modes used in our experiments. In electrical mode an amplified SiPM signal was sent directly to a high speed oscilloscope for timing pickoff. In electro-optical modes 10% of the analog SiPM signal (with or without amplification) was sent directly to the scope to for energy information. The other 90% was sent to the electro-optical link for timing pick-off.
