N7005A 是一款 60 GHz（-3dB，Brickwall）O/E 转换器，可兼容配有 AutoProbe III 1.85 mm 或 1 mm 输入的 Keysight UXR 示波器。 经过 DSP 校正的 N7005A 的频率响应要么是最高 60 GHz 的平坦 Brickwall 响应，要么是 4 阶 Bessel Thomson 响应，直到在 70 GHz 处转为 Brickwall 响应。 N7005A 与 70 GHz Infiniium UXR 示波器结合使用，可支持 4 阶 Bessel Thomson 响应，显示速度高达 56 Gbaud PAM4 的光信号流。因此，它特别适合在系统级测试和调试中，对高速光信号进行表征或问题诊断。
Infiniium UXR 基础软件 10.25 或更高版本提供了基本的光信号测量功能和归零校准。 Infiniium UXR 示波器上安装的 FlexRT 测量软件可对 PAM4 信令测量功能（如 TDECQ）进行深入分析。
Characteristics
60 GHz Brickwall bandwidth, covering 56 Gbd PAM4
Dc coupled real-time time signal acquisition system based on Keysight Infiniium UXR system, equipped with 1.85 mm or 1 mm input (≥40 GHz or higher)
Calibrated vertical scales at wavelengths of 1310 nm and 1550 nm
The FlexDCA software supports PAM4 measurement functions, such as TDECQ
Measure the S-parameter filter, which is suitable for optimizing the DSP filter on each O/E
Single-mode (9 μm) optical fiber input, FC/PC compatible
A UXR series oscilloscope is equipped with up to 4 optical fiber inputs
Only compatible with Infiniium UXR equipped with the AutoProbe III interface (≥ 40 GHz) (with SW 10.25 patch)
The N7005A is a 60 GHz (-3dB, Brickwall) O/E converter and is compatible with Keysight UXR oscilloscopes equipped with AutoProbe III 1.85 mm or 1 mm input. The frequency response of the N7005A corrected by DSP is either a flat Brickwall response at a maximum of 60 GHz or a 4th-order Bessel Thomson response until it switches to a Brickwall response at 70 GHz. When used in combination with a 70 GHz Infiniium UXR oscilloscope, the N7005A can support a 4th-order Bessel Thomson response
