Performance

Figure  shows the total deadtime of the DAQ system as a function of trigger rate measured in real beam runs. The typical trigger rate is 200 - 250 Hz. The deadtime linearly increases as the trigger rate increases and reaches up to 4% at 250 Hz which is consistent with the designed value. The overall error rate of the data acquisition flow is measured to be less than 0.05%.
