CAMAC - 3615 6-channel, 100 MHz Counter View Datasheet Request Ordering Information     ABOUT 3615 The Model 3615 is a single-width CAMAC module containing six independent 24- bit counters. These counters accept terminated NIM* signals at rates from dc to 100 megahertz (minimum pulse width three nanoseconds). Each counter has an overflow bit which is set on a carry from either Bit 16 or Bit 24 and generates a LAM, if enabled. The pattern of overflow bits in a module can be read. An overflow output for each counter can be wired to a rear-panel P.C. edge connector for cascading counters. Counters can be inhibited by Dataway Inhibitor by a front-panel signal. They can be individually cleared by Dataway command or as a group by Dataway clear or frontpanel signal. The input is protected for a ±50 volt transient or ±4 volts dc. Counter inputs are terminated in 50 ohms while inhibit and clear inputs are bridged high impedance. When precise timing of sequenced events is required, the Model 3655 Timing module provides a time base for the 3615 by asserting the Dataway Inhibit line for a programmable interval. A front-panel switch enables the inhibiting of counting by the Dataway Inhibit line.
