LeCroy 4413 16-ch 150 MHz Discriminator ============================================= CAMAC Commands ~~~~~~~~~~~~~~ N F(O) A(O) : Reads mask register. Q response in Remote mode only. N F(l) A(O) : Reads threshold setting when in Local or Remote mode. N F(16) A(O) : Writes mask register pattern (Wl-W16). Executable and Q response generated in Remote mode only. N F(17) A(O) : Writes threshold setting register, 11 bits: 10 bits of data (W1-W10) providing 1 mV resolution are used to program common threshold and 1 bit (Wll) to set the manual threshold value (front-panel screwdriver control) to the threshold register. In this case, the data presented on Wl-W10 is ignored. Executable and Q response generated in Remote mode only. N F(25) A(O) : Test function. Only channels not masked off by F(16) are triggered by internally generated 3 nsec wide pulse. Executable and Q response generated in Remote mode only. N F(24) A(O) : Set Local mode. N F(26) A(O) : Set Remote mode. Z : Clears mask register at S2 time, sets module into Local mode. CAMAC Responses ~~~~~~~~~~~~~~~ X : An X=1 response is generated for every valid F,N,A. Q : A Q=l response is generated if the valid command can be executed. ----------------------------------------------------- Note: Updating/Burst Guard operational modes choose only by rear-panel Updating/Burst Guard Switch which allows the selection of the operational mode.
