产品详情

HF2LI 数字锁相放大器 (苏黎世仪器 Zurich Instruments)

总览

瑞士苏黎世仪器 (Zurich Instruments) 的 HF2LI锁相放大器（高频，双通道）是可以测量从直流到 50 MHz 频率范围的数字锁相放大器。它具备双输入通道，可以替代许多需要用到2 台单通道锁相放大器的情况。128 位的数字信号处理提供卓越的精确度，因而提高噪声性能和动态储备。通过这些所未有的功能，HF2LI 把锁相放大器提高到了新的水平，并能够应用到频率要求更高的更多的场合，以模拟仪器的频率范围受到了大的限制。高速数据采集可通过高速 USB 连接计算机来实现。HF2LI 具有强大的图形用户界面和多种编程接口，使用非常方便

技术参数

功能图解

高精度输入

HF2LI 的双输入通道经优化设计达到超低噪声水平。高达模拟输入带宽 4 倍的210 MSa/s 采样率充分保证信号的完全捕获信号并避免混叠。

信号输出

HF2LI 的2路高频输出来源于多6 个直流到 50 MHz 的正弦波线性组合。当启用 HF2LI-MF 多频选件时，即可以为每个正弦波分量设置振幅、频率和相移。

解调器和滤波器

HF2LI 提供 6 个双相解调器。每个解调器都可通过自带的滤波器做独立设置，包括从 1 μs 到 500 s 的时间常数（相当于 80 μHz 到 200 kHz的解调信号带宽）和1 到 8 阶滤波器。滤波器基于的128 位数字架构。相对普通模拟仪器来说，优势是具备更高的动态储备、零点漂移、精确相移和正交性。

集成工具组

2048 点存储深度的集成示波器提供直观的输入信号时域和频域视图。用户可以随时看到输入的和生成的信号，由此可迅速找到正确的设置。频率响应分析仪可提供精确的频响图。FFT 频谱分析仪可提供由锁相放大器解调出的高分辨率频谱图。
