Downloaded from https://www.everyspec.com MIL-STD-1311D PULSE CHARACTERISTICS When pulse voltages or currents are specified on the TSS, the values of time of pulse, repetition rate, and pulse amplitude shall be specified. The pulse amplitude shall be defined as the maximum value (excluding spike) of a smooth curve through the average of the fluctuation over the top portion of the pulse (see figure 1296-1). The allowable spike width measured at the base of the spike shall not exceed 10 percent of the pulse duration (tp). The width of the pulse, at an amplitude of 0.9 of the pulse amplitude, shall be not less than 80 percent of the (tp).
The time of rise (tr) shall not exceed 0.1 of the tp, and the time of fall (tf) shall not exceed 0.2 of the (tp). (For magnetrons, see method 4304.) METHOD 1296 FIGURE 1296-1. Pulse voltage or current characteristics. METHOD 1296 1296-1 19 April 1968
