High Intensity Radiated Field (HIRF) Testing

随着产品的复杂性增加，我们已经投入了综合材料的使用，以使我们的EMI / EMC测试服务与所需的越来越苛刻的水平相匹配。yabo娱乐vip

因此，我们的能力甚至可以适应商业，军用和飞机制造商标准所需的最高HIRF测试水平。与积极参与RTCA特别委员会的参与专家135，以及SAE4 HIRF / EUROCAE WG-14联合工作组，我们致力于留在行业的前沿，帮助您了解技术要求。

元素可以在测试级别进行HIRF测试，完全满足并超出以下要求：

• FAA HIRF Rule and AC 20-158, ALL CW, SW, and Pulse test levels, for ALL Environments
• RTCA / DO-160D / E / F / G，所有CW，SW和脉冲测试水平，适用于所有类别，包括猫。L.
• 波音D6-16050-4 / -5 / -6，所有CW，SW和脉冲测试水平

• ADS-37A-PRF，表I，A款A＆B，所有CW，SW，AM，FM和脉冲测试水平
• Def-Stan 59-41 & 59-411 DRS02.B, ALL Air, Sea and Land CW, SW, AM and Pulse Levels

HIRF测试设施

Our high intensity radiated field (HIRF) facilities include a suite of specialist antennas to allow HIRF testing to be performed in the conventional line-of-sight direct illumination method as well as the reverb method.

混响腔室使用反射桨叶“搅拌”RF以确保在整个腔室中没有零且场强保持均匀。桨叶可以连续（搅拌）或以阶梯式的方式（调谐），可以调整速度或粗糙度以适应您的要求。

Mode Tuned Testing

在模式调谐测试期间，搅拌器在步骤/停止/步骤/停止类型的操作中操作。模式调谐测试的好处是：

• 适用于慢速循环设备。
• 在长期停留时间连续田间。

模式搅拌测试

在模搅测试期间，搅拌器连续旋转。模式搅拌检测的好处是：

• Much quicker than mode tuned method.
• 停留时间很短。

增加使用的复合材料aterials in aircraft fuselages, sensitive electronic equipment is provided less RF shielding from the high field strengths generated by, for example, airfield RADAR. This can result in unexpected exposure to several thousand volts per meter of RF energy which has the potential to cause equipment failure. HIRF testing replicates the pulse modulations and energy levels that high power RADARs generate to ensure that aircraft equipment is sufficiently EM – hardened to withstand them.

The latest revision of RTCA-DO-160 (G) states that all 6 faces of a system must be subjected to radiated susceptibility testing. Due to the uniform nature of the field generated in the reverb chamber, this can be achieved with only one test run, as opposed to six when using the conventional semi-anechoic chamber method, resulting in a significant time and cost saving.

The HIRF equipment can also be programmed to conduct MIL-STD 461 and Def-Stan 59-411 radiated susceptibility testing as per the respective alternative methods for reverberation chambers.

所有HIRF测试都在完全计算机控制下进行，灵活性提供几乎任何频率步长，脉冲占空比或调制类型。

使用HIRF测试的混响方法的好处

Our reverberation chambers have intrinsic properties of isotropy and homogeneity that provide several unique features for testing:

• 随机偏振，即所有波之间的相位是随机的。
• 空间均匀，即腔室中的能量密度到处都是均匀的。
• 各向同性，即各方向的能量流是相同的。
• 无论房间的位置如何，场测量结果都将相同。
• Spatial reconfiguration of the EUT will have minimal effect on those measurements.
• 一个或多个腔室之间的EUT测量将是相同的。
• 混响室在完全测试期间模拟所有波偏振和入射角。
