 ====== Scalers and dead time ======
-The "D" connector of the trigger module is directly connected to 16 inputs of a scaler module (see mapping of the inputs and outputs of the trigger module in section [[Trigger#Inputs and outputs|Inputs and outputs]]). Scalers are connected to each of the trigger source inputs, as well as trigger box inputs. These scalers can be used to recover the number of trigger signals occurring on each of the source and trigger box inputs, besides the information coded for each event in the trigger register.
+The "D" connector of the trigger module is directly connected to first 16 inputs of a {{:wiki:Manual_LeCroy_Scaler_4434.pdf|32-channel scaler LeCroy 4434 module}} (see mapping of the inputs and outputs of the trigger module in section [[Trigger#Inputs and outputs|Inputs and outputs]]). Scalers are connected to each of the trigger source inputs, as well as trigger box inputs. These scalers can be used to recover the number of trigger signals occurring on each of the source and trigger box inputs, besides the information coded for each event in the trigger register.
 For the determination of the dead time, both a free running and vetoed 10 kHz pulser signal are also connected to scalers. This is the preferred method because the pulser is not subject to possible double triggering effects like the raw trigger.
