LeCroy 4413 16-Channel, 150MHz CAMAC Discriminator

Description

The LeCroy Model 4413 is a 16-input discriminator in a single-width CAMAC module. Three modes of operation are provided; Updating, Burst Guard and Retiming Mode. The module accepts NIM level inputs and operates to 150 MHz. The outputs of the 4413 are differential ECL levels which are compatible with LeCroy's ECLine series of programmable logic modules. Output widths are adjusted from 3.5 nsec to 100 nsec in the Update mode.
Each of the 16 channels share a common threshold which is set by a front-panel potentiometer or via CAMAC commands. The threshold range extends from -15 mV to -1 V. The unit also has a common front panel VETO input as well as a TEST input. However, the TEST mode can also be initiated by CAMAC commands and only desired channels may be tested using a CAMAC write mask command. In addition, the unit has two bridge outputs which generate a current proportional to the input multiplicity.
The high density is made possible through the use of eight HVL201 hybrids. These hybrids enhance the reliability of the Model 4413 as well as provide for the 150 MHz counting rate operation.
