Overview |
|
|
The Mod. C469 is a single width CAMAC unit housing 16 independent channels able to generate a pulse with programmable delay and width. The delay and the width can be programmed with 8 bit resolution in a range up to 500 ns. The unit has a minimum programmable delay value which is 15 ns +12% of the full scale value due to internal timing. All the input and output signals are standard ECL. The unit has a NIM input signal on the front panel which allows the test of the unit and the generation of the outputs. One of the channels' outputs can be selected via CAMAC and fed to 2 multiplexed NIM outputs. A NIM input VETO signal can be used to disable the outputs. (ISN-GRENOBLE design). |
