Subject: Photodiode test signal 
We used a signal generator to provide a 4MHz dummy-RF signal. This was divided by a factor of 2 for laser-"bunch" synchronization and by a factor of 200 for to provide the stop-tigger attached to the DAQ. With this Dummy-RF we were able to measure the relative arrival times of the laser at the photodiodes located in the laser towers. Note that the signal of the southern photodiode arrives first. This is because the scale of the time axis is given in (10/3ns)-bins since the last common-stop.
