   * Bias detector. Typical bias: **1200-1800 V** (up to 2200 V)   * Bias detector. Typical bias: **1200-1800 V** (up to 2200 V)
  
-  * Use **[[electronics overview|scope]]** to look at signal patched out to data U6 (channel #54 in data U6 patch panel) +  * Use oscilloscope to look at analog signal patched out to data U4 
-      * This signal is sent to the CANBERRA 454 Quad CFD in data U6 +
-      * One of the output from this CFD is sent (via patch panel #62) to the TAC and scaler (channel OBJ.Scint) in S3. The other output goes through a passive delayed, and is sent (via patch panel #67) to the Phillips TDC+
       * Check raising time and amplitude. Good signal: ~10 ns raising time; 400-500 mV amplitude       * Check raising time and amplitude. Good signal: ~10 ns raising time; 400-500 mV amplitude
 +      * Check if there are reflections (typically seen at ~300 ns after main peak)
    
   * Using the scope, check the CFD setting:   * Using the scope, check the CFD setting:
