描述：HA9可編程衰減器是一種高分辨率，擴展范圍，功率計和測試一般測試和實驗室工作的可編程衰減器的理想選擇。衰減器有一個0.01分貝標稱分辨率和100分貝的衰減范圍擴大。標準工作波長為1200至1700年納米（750-1700 nm的可使用60分貝衰減器的HA9W減少衰減范圍）。
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).
