描述:
HA9 衰减器是高分辨率、扩展范围、可编程衰减器,非常适合测试功率计以及一般测试和实验室工作。HA9 衰减器的标称分辨率为 0.01 dB,扩展衰减范围为 100 dB。标准工作波长为 1200-1700 nm。
HA9 衰减器非常适用于要求苛刻的应用,例如多通道 AM 系统和高比特率数字脉冲编码调制 (PCM) 系统。离散内部光学反射最小化到优于 60 dB,并且几乎消除了空腔效应。所有 HA 衰减器都为 CATV AM 系统提供高回波损耗和低频谱纹波。
这些衰减器的固有线性设计,结合内置校准和偏移功能,允许用户在很宽的功率范围内将显示器与光功率计相匹配。此功能在需要控制测试设备的绝对光功率源的测试中很有用。内置光束阻挡开关提供从任何衰减设置到无限衰减 (> 90 dB) 的快速访问题。

Product Description:
The HA9 attenuators are high-resolution, extended-range, programmable attenuators ideal for testing power meters and for general test and laboratory work. The HA9 attenuators have a nominal resolution of 0.01 dB and an extended attenuation range of 100 dB. The standard operating wavelength is 1200-1700 nm.
HA9 attenuators are ideal for use in such demanding applications as multichannel AM systems and high bit-rate digital pulse code modulation (PCM) systems. Discrete internal optical reflections are minimized to better than 60 dB, and cavity effects are virtually eliminated. All HA attenuators are offered with high return loss and low spectral ripple for CATV AM systems.
The inherently linear design of these attenuators, combined with built-in calibration and offset functions, allows the user to match the display to an optical power meter over a wide power range. This feature is useful in tests requiring control of the absolute optical power source for the test device. The built-in beam blocking switch provides fast access from any attenuation setting to infinite attenuation (> 90 dB).
