CHECK LIST | COMMENTS | RESULT |
---|---|---|
Perform a carton drop test on the export cartons:10 times(1 corner 3 edges 6 faces)-S1 | PASSED | |
Smell check-check if there are any strong offensive odor-II | PASSED | |
For 3M tape adhesive test: perform test on coating (painting/plating/ screen printing, etc) with 3M tape.-S2 |

Emission 20dB BandwithC.FR47 1.发射器 20dB 带宽 1)限值 第 15.231(c)节:对于工作在 70 MHz 以上且 900 MHz 以下的设备,发射带宽不应大于中心频率的 0.25%。对于工作在900 MHz 以上的设备。带宽是在距离调制载波 20 dB 处确定 的。可知,对于中心频率工作在 433.92MHz 的设备,其 20dB 带宽限值是 1.08MHz。
B.将频谱分析仪的 RBW 和 VBW 设置为适用值,大保持峰值。 C.采用频谱分析仪中的 PEAK 输出读数和 20dB BW 功能。 |
The factory has no equipment to test. | FAILED |
transmitterTimeoutC.FR47 FCC 发送器时间测量
B.设定中心频率为 433.92MHz,设定范围为 0Hz。 C.使用 Peak 将频谱分析仪的 RBW 和 VBW 设置为适用的值。 D.直接从频谱分析仪读取从传输到静音的时间 |
The factory has no equipment to test. | FAILED |
The transmitter radiated spurious emission 发射机辐射杂散发射
B.在 30MHz 以上的频率范围内,使用 Bi-Log 测试天线(30MHz 至 1GHz)和喇叭测试天线(1GHz 以上)。测试天线距离 EUT 3 米。测试天线高度在地面以上 1m 至 4m 之间变化以确定场强的大值,转盘的方位角范围为 0°至 360°,接收天线具有水平 和垂直两个极化。当进行 1GHz 以上的测量时,EUT 被置于喇叭天线的 3dB 波束宽度范围内,并且 EUT 在 ANSI C63.4 中针 对辐射发射推荐的 3 个正交位置进行测试,并且呈现了坏情况数据。 |
The factory has no equipment to test. | FAILED |
Perform a function test II You put the receiver in the wallsocket, and the pushbutton generate kinetic energy. The last time the problem is that the pushbutton is not always good. You need to push them more then ones, or there are other problems. |

Wireless distance Check--无线距离测试(有墙和无墙测试>100m)-II | PASSED | |
Check relevant international certification (Such as CE/UL/FCC/ROHS) | N/A | |
Perform an internal check. - S1 | N/A |
