CAMAC - 3655 8-channel Timing Pulse Generator View Datasheet Request Ordering Information     ABOUT 3655 The Model 3655 is a single-width CAMAC module containing a 16-bit counterand eight 16-bit set-point registers that are compared with the counter. The comparisons produce output pulses, and any of them can be used to either stopor clear the counter. The comparisons also produce LAM status bits, which can be individually enabled to produce LAM requests. A flag bit determines whether the counter stops with the last output pulse or whether it is cleared to produce repeating sequences of timing pulses. In the former mode of operation, additional pulse sequences are initiated either by programmed command or by external signal or contact closure. The 3655 provides its own crystal clock, and the input frequency to the counteris software-controlled for any decade from one hertz to one megahertz. Input to the counter can also come from an external source. Two of the comparisons can set and clear the Dataway Inhibit. Numbers in the eight registers (or fewer, if less than eight pulse sources arerequired) must be stored in increasing numerical order for proper timing of output pulses. Two control registers provide programmable control of the clock frequency (onehertz to one megahertz), the number of channels that generate a pulse (one to eight), the assertion of Dataway Inhibit, and whether to stop or recycle after the last pulse.
