摘要

采用重复随机方波脉冲发生器(R/sup 2/SPG)技术确定5个系统的扰动阈值。这些系统包括一台AT级个人计算机、一个大型数字控制通信系统、一个通信系统的数据显示子系统、两台雷达和一个点防御系统。如果加厚阈值在测试程序和R/sup 2/SPG的能力范围内,即使在未硬化的系统中,通常也需要3到10安培的加厚。视觉显示器上的“雪”发生在较小的电流下。不出所料,与数字电路较少的旧系统相比,一些更现代的系统具有更低的阈值和更频繁的故障。然而,一些数字系统被发现对非常高水平的破坏免疫。没有一个系统在测试中损坏。这初步证实了“不安先于损害”的说法。

Upset thresholds of various systems as measured by the R/sup 2/SPG technique
The upset thresholds of five systems were determined using the Repetitive Random Square-wave Pulse Generator (R/sup 2/SPG) technique. These systems included an AT class personal computer, a large digitally controlled communication system, a data display sub-system for a communication system, two radars and a point defense system. If the upset threshold was within the limits of the test program and the capabilities of the R/sup 2/SPG, significant upsets generally required 3 to 10 Amperes, even in unhardened systems. "Snow" on visual displays occurred at smaller currents. As expected, some of the more modern systems had lower thresholds and more frequent upsets than older systems with less digital circuitry. However, some digital systems were found to be immune to upset of damage up to very high levels. None of the systems were damaged by the test. This tentatively confirms the statement that "upset occurs before damage.".<>
