Abstract: System and apparatus enabling the use of a single cable to communicate triggering information between each of a plurality of signal acquisition devices and, illustratively, an external trigger control unit. A combined trigger signal is produced only when each trigger condition of each signal acquisition device is true. Thus, all of the signal acquisition devices will be triggered substantially simultaneously.

Abstract: A coaxial cable 24 has an outer conductor 74 surrounding an inner conductor 70. A portion 76 of the inner conductor 70 is stripped of insulation and extends beyond the end of the outer conductor at a cable end 30. A circuit board 12 has a major surface and defines an elongated slot 34. A connection end of the slot is defined by a stop portion of the board 36, and a conductive pad 60 is provided on the board surface adjacent the stop portion at the end of the slot. The stripped portion 76 of inner conductor 70 is connected to the conductive pad 60, and at least a portion of the outer conductor 74 is received in the slot, and may be connected to another contact on the board. The stop portion of the slot is defined as a peninsular connection tab 54 by an elongated hole 50 formed on each side of said stop portion 36 of said slot. The distance between the sides of the conductive pad 60 and the near edges of the elongated holes 50 is selected to provide a predetermined transition impedance.
