GENERAL DESCRIPTION
N-TM 305 8CH DISCRIMINATOR (UPDATING) is composed of 8 independent UPDATING DISCRIMINATOR circuits and 1 common “VETO” circuit. The threshold level and the output pulse width can be adjusted independence each channel. The threshold level can be adjusted from -10mV to -1V and the output pulse width can be adjusted from 13ns to 200ns by potentiometers of front panel.
