   Thanks,   
      
   I`m helping some colleagues setting a Mossbauer spectrometer. From the signal   
   side we have:   
   proportional detector --> pre amp (+ HV PS) --> amp --> MCA   
   I`m not sure if both the pre amp and the amp are working properly and   
   would like to test, but I don`t have access to a NIM pulser (like the   
   ortec 480). AI also can't test the chain with the detector...   
   My question are:   
   1) Can I use a "normal" sinusoidal or square generator to test the   
   chain? I don't thing so but...   
   2) I could build a simple pulser using a relay (just search on line for   
   the 480 schematic), but I don have access to a mercury relay. Is this   
   going to work with a normal relay?   
      
   Tanks JM
