   * If necessary, adjust delays of Phillips TDC (in principle, the TACs delays don't need to be adjusted):   * If necessary, adjust delays of Phillips TDC (in principle, the TACs delays don't need to be adjusted):
-      * Using the [[S800 DAQ tools#Trigger GUI|ULM trigger GUI]] assign TDC-start to one of the Inspect Trigger channels (patch panel #55 - #58) and trigger the scope with it (be aware that the TDC-start signal seen in the scope has an additional delay of ~200 ns due to the length of the cables between the ULM module in S3 vault and dataU6 patch panel)+      * Using the [[S800 DAQ tools#Trigger GUI|ULM trigger GUI]] assign TDC-start to one of the Inspect Trigger channels (patch panel #55 - #58) and trigger the scope with it 
       * Connect the XFP and/or OBJ signals going to the Phillips TDC (via cables plugged to patch #66 and #67, respectively) to the scope       * Connect the XFP and/or OBJ signals going to the Phillips TDC (via cables plugged to patch #66 and #67, respectively) to the scope
-      * Adjust the TDC delays of OBJ and/or XFP with respect to the TDC start, using the delay boxes connected to the CANBERRA CFD 454 in data U6 +      * Adjust the TDC delays of OBJ and/or XFP with respect to the TDC start using the delay boxes connected to the CANBERRA CFD 454 in data U6 (~200 ns delay is good) 
-      * Be aware that the after adjusting OBJ and XFP delays in the scope, the signal will be further delayed by ~200 ns due to the length of the cable between dataU6 patch panel and the Phillips TDC in the S3 vault.+      * Check the corresponding ToF spectra in SpecTcl to confirm that the timings are properly adjusted.
