8563EC使用手册
频谱仪8563EC使用手册一、频谱仪简介Agilent 8563EC 是便携式的彩色显示微波频谱分析仪，提供昂贵的更大台式分析仪才具备的测量能力和特性。
8563EC将8560EC系列RF频谱分析仪的优良特性和功能扩展到微波频率范围。
该分析仪具有 9kHz 至 26.5GHz（预选从2.75 GHz 至 26.5GHz）的标准频率范围，并具有至 30Hz 的可选低端频率覆盖。
8563EC的镜频增强、双平衡谐波混频器的噪声系数性能与基波混频前端相似。
它使用坚固的MIL机箱兼具优异的相噪、灵敏度、1Hz分辨率带宽、合成型调谐和宽动态范围，能适应各种环境条件的要求。
如图所示为Agilent 8563EC 微波频谱分析仪。
图 1 ：Agilent 8563EC 频谱仪频谱分析仪就像示波器一样是用来观察信号的一个基本工具。
其中示波器提供了一个时域的窗口，而频谱分析仪则提供了一个频率的窗口，如图2所示。
图2二、基本操作介绍首先打开仪器：1、按‘LINE’键，打开频谱仪。
2、频谱仪经过半分钟来完成一系列的自我检测和调节程序。
完成后，屏幕上会出现分析仪型号和软硬件结合数据（如，890802 显示为1989年8月2日）。
如果你在任何时候需要了解安捷伦的服务技术或你的分析仪有任何的问题，它将对于了解软硬件数据从而得到更多准确的信息很有帮助。
3、允许分析仪有5分钟的预热时间。
4、在后面将给出参考标准的校准调节程序。
5、完成微量调准程序，从而优化显示区域。
6、通用接口总线地址可能由于细微的操作而被改变。
·频谱仪的工作范围：幅度范围 -148dBm到+30dBm频率范围 9kHz到26.5GHz·基本测量：一个基本测量包括调谐频谱仪使在屏幕上出现一个信号，然后使用‘marker’对其频率和幅度进行测量。
我们可以经过四个简单的步骤完成对一个输入信号的测量。
1、设置中心频率；2、设置频率范围；3、激活‘marker’；4、设置幅度。
