JDSU 可编程衰减器
描述：HA9可编程衰减器是一种高分辨率，扩展范围，功率计和测试一般测试和实验室工作的可编程衰减器的理想选择。衰减器有一个0.01分贝标称分辨率和100分贝的衰减范围扩大。标准工作波长为1200至1700年纳米（750-1700 nm的可使用60分贝衰减器的HA9W减少衰减范围）。
The JDS Uniphase HA9 PThe JDS Uniphase HA9 Programmable Attenuator is a highresolution, extended-range, programmable attenuator ideal for testing power meters and for general test and laboratory work. The attenuator has a nominal resolution of 0.01 dB and an extended attenuation range of 100 dB. The standard operating wavelength is 1200-1700 nm (750-1700 nm is available to use with a reduced attenuation range of 60 dB for the HA9W attenuator).
