MET的SAR设备完全配备了一个Schmid&Partner Engineering AG(SPEAG™)DASY专业系统,利用RX 90机械臂进行扩展。此外,我们的DASY系统有多个双SAM模体和平面模体,允许快速测试周转时间。 DASY能够针对头部和身体佩戴设备的所有全球SAR标准评估产品。

MET测试一系列产品,例如蜂窝/ PCS GSM / DCS CDMA / GMSK / TDMA / AMPS电话,PDA,笔记本电脑,面对面设备,W-LAN(2.4GHz和5GHz)等。

结合SAR测试,MET还对固定和/或移动应用执行最大允许曝光(MPE)评估。这些评估是在准备在距离最终用户> 20cm的距离处使用的辐射结构上执行的。我们测试的典型设备是在UHF和VHF频带中工作的车载天线。

什么是SAR测试?

SAR测试是暴露于RF场的生物对象内吸收的电磁能量的幅度和分布的射频(RF)剂量测定量化。

这些水平表示为瓦/千克(W / kg)。国际监管机构要求对大多数便携式和移动无线技术进行SAR评估。

可以影响SAR的参数包括:

  • 无线电服务的类型(蜂窝,PCS,LMR,WLAN等)
  • 调制类型(CDMA,GMSK,TDMA,AMPS等)
  • 对人的身体取向(持有耳,持有面,带夹,搭扣等)
  • 射频功率水平(瓦特或mW)
  • 变送器,天线(抽出/收回)或附件(夹子,电池等)

FCC将广泛的独立操作的便携式发射器分类为SAR测试的潜在候选者。例如,便携式计算机可能需要SAR测试。戴在皮带上的手机,传呼机和其他设备也可能需要SAR测试。当便携式发射机天线和辐射结构距离人不到20厘米,除了四肢(手,手腕,脚和脚踝),并且根据设备的频率和阈值水平,可能就需要SAR测试。
