The transparent mode 3 dB bandwidth is about 60 MHz, which is slightly larger than the 50 MHz reported in. While this means that there is more signal information available to the trigger logic, it also implies that there is no oversampling margin in the 120 MSPS data stream, and aliasing may occur. However, the low-pass filter has been measured to be approximately of 3rd order, which suppresses higher frequencies quite well. The effective gain of the system was measured to be 18 dB for DRS4 readout and 13 dB for transparent mode signals.
