LeCroy 4312 16-Channel, 200 MHz CAMAC Discriminator:
$50

The LeCroy Model 3412 is a 16-input discriminator in a single width CAMAC-module. The module accepts NIM-level inputs and operates to 200 MHz. The outputs of the 3412 are differential ECL-levels which are compatible with LeCroy’s ECLine series of programmable logic modules. Output widths are adjusted from less than 5 to over 100 nsec.

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 -10 mV to -1.034 V for Model 3412 and -15 mV to -1.034 V for Model 3412E. 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 the desired channels can be tested using a CAMAC write mask, or Ext Rear panel mask. If either the CAMAC or Rear Panel Inhibit is true the selected channel will be inhib- ited. In addition, the unit has a sum output which generates a current proportional to the input multiplicity.

The high density is made possible through the use of 16 MDC100 custom IC chips. These chips enhance the reliability of the Model 3412 as well as provide for the 200 MHz counting rate operation.

The Models 3412 and 3412E have the same circuitry except for one potentiometer value. R331 is 10 kΩfor the 3412 and 20 kΩfor the 3412E.
