【产品】N7747A和N7748A高灵敏度光功率计助力N77平台提供最高性能紧凑型自动化仪器

时间： 2019-03-17 来源：Keysight

技术问答

借助N7747A和N774 8A，N77平台现在可以提供最高性能的紧凑型自动化仪器。出色的光性能结合当前最高灵敏度（-110 dBm）以及对应的低噪声和高稳定性，可以提供精确的弱信号和微小信号变化测量与监测。高灵敏度需要高相对功率精度和低偏振相关与低频谱波动支持。高灵敏度结合10 dB间隔的9个功率范围，可以提供最高动态范围和出色的线性度。

上述仪器将业经验证的、光性能出众的 81634B 传感器模块和有大存储器，可以构建具有高数据传输速率的紧凑型 N77系列平台相结合。单机架单元可以安装最多8端口的高灵敏度光功率计。光连接通过可互换的 81000xl 连接器接口系统完成，因此仪器能够方便地应用不同类型的光纤连接器。每个光端口配有 2 个存储器缓冲区，每个缓冲区可以记录多达 100 万个样本。该模块可以在一个缓冲区记录数据的同时通过另一个缓冲区上传数据，以实现连续监测，从而敏锐发现小瞬态信号。N7744A 和N7745A 使用相同的功能，区别在于高灵敏度型号采用了低带宽，以确保低噪声性能。

与 81634B 和 8162 *B 光功率探头类似，N7747A 和 N7748A 每个光通道都包括一个模拟输出，用于提供与光功率成比例的0至 2 V信号（取决于所选的功率范围），并支持高达 5 kHz 带宽模拟信号监测。该模块配有 USB、LAN 和 GPIB 接口，支持使用与 816x、N774 4 A 和 N774 5 A 相同的 SCPI 命令集控制仪器。此外，该模块可以使用最新版本的 N77xx Viewer 用户界面程序和 816x VXI 即插即用驱动程序。

1、参考条件：10 μW (–20 dBm) 功率，连续波，50 μm 级光纤，NA = 0.2，环境温度 23 °C ±5 °C，校准日（一年内因老化增加±0.3%，第二年增加±0.6%），激光源频谱宽 < 10 nm (FWHM)，功率传感器波长设置必须与激光源波长（±0.4 nm）对应。

2、工作条件：光纤 ≤ 50 μm，NA ≤ 0.2，连接器带有直角或角抛光 2.5 mm 平面金属箍（光纤尖端偏移不得超过 0.3 mm，2.5 mm 截面），校准后一年内，第二年增加 0.3%，工作温度参见技术指标，湿度：无冷凝

3、不包括噪声和漂移。

4、恒定波长 (1550 ± 30 nm) 和恒定功率全部偏振状态。直角连接器，温度 = 23 °C ±5 °C。使用角连接器（8°）时典型值增加±0.01 dB。

5、测试条件：波长 1550 ± 30 nm，固定偏振态，恒定功率，温度 23 °C ±5°C，激光源线宽 ≥ 100 MHz，8°角连接器。

6、连续波，–90 至 +10 dBm，1000 至 1630 nm。

7、平均时间 1 s，温度 = 23 °C ±5 °C，ΔT ±1 °C，观察时间 300 s
