在从设计到生产线末端测试的各个阶段确保汽车电子天线罩和保险杠的质量

R&S®QAR50 非常适用于在生产线末端 (EOL) 在汽车电子雷达频率范围内准确测试汽车电子天线罩和保险杠的质量。测试仪体型较大,能够轻松容纳笨重庞大的保险杠,并进行空间分辨测量以评估设计标识的均匀性。借助创新的硬件概念,经济实惠的 R&S®QAR50 可以实现具有明显优势的测量速度,并通过模块化软件概念满足用户的具体要求,确保快速准确地测试天线罩和保险杠。

特性和优点

结果真实可靠

测量集群为样品提供更多空间

R&S®QAR50 利用约 200 个接收和发射天线以快速测量材料、保险杠和标识的特性。微波成像技术运用电子聚焦,能够更加灵活地定位测量天线,从而为重要的被测材料留有充足的空间。

电子聚焦增强了装置的稳健性。仅使用单个天线接收和发射信号时,反射能量须准确返回原点。即使是轻微的角度偏差,也会对测量值产生巨大影响。R&S®QAR50 装备大型天线阵列,可允许更大的位置公差,同时提供高精度的测量结果。在此位置公差范围内,仪器可确保结果正确且可靠。用户甚至可以在生成的图像中对错误的样品位置进行光学跟踪。

打开灯箱

测试仪配有数百个接收和发射天线,通过全电子聚焦方式快速测量材料、保险杠和标识的特性。

无需移动即可对保险杠和天线罩进行特性测量。

借助微波成像技术,R&S®QAR50 无需移动即可多方位表征样品。软件不仅提供空间分辨反射和传输相位图像,还支持对被测设备进行频率分辨分析。

生成的图像可用于详细分析样品的均匀性,而时间门控频率响应则确保在制造过程中优化产品并保持稳定质量。

强大的反射测量有助于在生产中掌握样品的正确位置。

Material characterization

Evaluate the characteristics of newly developed materials, colors and coatings.

New colors and coatings need to be characterized for their radar transparency throughout the development process. In order to develop radar transparent primers and paints, the permittivity of each layer plays an important role. So far, vector network analyzers have been used in order to calculate permittivity and loss factor of each layer. The R&S®QAR50-K20 phase measurement together with the permittivity calculator allows for an easy and fast characterization of each layer without the challenges coming with of quasi-optical, or waveguide based setups.
