This page summarizes the results of test measurements carried out with out LED boxes. The LED boxes were connected to the LED trigger boxes, which were operated with a trigger rate of 10 - 100 triggers/second and an LED operating voltage of 120 V. The fiber of a single PMT (operated at 120 V) was connected sequentially to the 30 fiber outputs of the LED box, and the properties of the PMT pulseheight signals were measured using an oscilloscope.
