For the graphical interface one has to go to \verb!locahlhost:1234/thresh/threshold.htm!. There one has to choose the correct Board, DAC-Chain and Channel (even numbers are the FAST channels, odd numbers are the SLOW channels). The Reference has to be set to 3300\,mV. For PaDiWa-AMPS the signal polarity and the approximate value of the baseline is shown in Figure \ref{fig_fast_slow}. The FAST signal is a positive Signal with an baseline at around 60\,mV. One has to find the baseline which is indicated by a very high rate in the TDC Hit Counters (\verb!localhost:1234/tdc/tdc.htm!). Then one has to increase the threshold to set a proper value. The SLOW signal is a negative Signal, so after finding the baseline at around 2890\,mV one has to degrease the threshold to set a proper value. For the FAST channels a threshold of about 10\,mV above the threshold is a reasonable value. The SLOW channels are more sensitive to noise, here values above 20\,mV are reasonable. \begin{figure}[h] -- 2.43.0
