Bird SK-4500天馈线分析仪
• Easy to operate and field ready for first-time, occasional and experienced users.
• 新手和经验丰富的用户在*时间易于操作和现场准备。
• FDR (Frequency Domain Reflectometry) measurement method results in a highly reliable assessment of the health of critical components in your system; ultimately providing a “heads-up” before a failure occurs.
FDR（频域）在系统中的关键部件的完好安全可靠的评估测量方法；*终为“heads-up”的故障发生之前 发生.
• Fault location or DTF mode indicates VSWR or Return Loss levels at each point along the cable and antenna system length.
故障定位或DTF模式指示驻波比或回波损耗水平在各点沿电缆长度和天线系统。
• Cable Loss function measures insertion loss of the cable system over a given frequency range.
电缆损耗函数测量电缆系统在给定频率范围内的插入损耗。
• Units cover frequency ranges of 1 MHz - 4500 MHz.
单位覆盖频率范围为1 MHz - 4500 MHz
• USB communication port for connection to storage device and battery charging.
USB通信端口连接到存储设备和电池充电。
• Three Year Warranty!! 
三年保修！！
