  • Page 9: Description

    3.0 DESCRIPTION The Model 8282-1 Transient Pulse Generator is a completely self-contained unit with more than sufficient output power to fully comply with the require- ments of all sections of MIL-STD-461B, Method CS06. The dimensions of the unit are 12.25"W x 8.70"H x 13"Deep. The unit weighs approximately 30 pounds.
  • Page 10 These include: a) Terminals for connecting to a synchronizing power source other than the 50 Hz or 60 Hz which serves the Model 8282-1. b) A three pin connector for cabling to remote controls.

    5.1 GENERAL – The toggle switch on the rear of the unit must be in the INTERNAL position in all cases except when the power source to the EUT is not common to the 8282-1. This exception is described in Par. 5.4 and illustrated in Fig. 6.

  • Page 13: Interconnection For Series Injection

    The SERIES output terminals of the Model 8282-1 are capable of carrying up to 50 amperes power current, provided that large enough wires can be used with firm connections to the terminals. The wire hole in the terminals will accommodate a #12 A.W.G.

    EUT. If the line voltage to the EUT is greater than the voltage into the line cord of the Model 8282-1, add a step- down transformer at the points marked X in Fig. 6 to reduce the voltage applied to the rear terminals.

  • Page 15: Repetition Rate

    When the test plan requires both a positive and a negative spike, it is necessary to reverse the connections to the output terminals of the Model 8282-1 Spike Generator. 5.8 REMOTE TRIGGERING – In lieu of the panel button controls for repetition rate adjustment or phase shifting on a.c.
