怎么使用N9010A测量高阻抗DUT

嗨 - 41800A有源探头是一种解决方案，假设你可以使用探头连接到你的DUT。
它会给出准确的结果。
但是，41800A的频率范围限制在500 MHz。
还有另一种有源探头85024A，其频率范围为300 kHz至3 GHz。
与41800A一样，您必须使用探头尖端与DUT建立连接。
这两种探头都从信号分析仪上的探头电源连接器获得电源。
安捷伦曾经提供41802A 1 MOhm阻抗适配器。
它基本上是41800A的阻抗匹配部分，但用一个母BNC连接器代替探头和探头电缆。
您可以将它与您自己的高阻抗探头（例如示波器使用的探头）一起使用。
但是，该产品已停产几年。
与41800A一样，41802A通过信号分析仪上的Probe Power连接器接收电源。

  Hi -

The 41800A active probe is one solution, assuming you are OK with using a probe to connect to your DUT. It will give accurate results. The frequency range of the 41800A, however is limited to 500 MHz. 

There is another active probe, the 85024A, which covers frequency ranges from 300 kHz to 3 GHz. As is the case with the 41800A, you would have to make the connection with your DUT using the probe tip.

Both of these probes obtain their power from the Probe Power connector on the signal analyzer. 

Agilent used to offer the 41802A 1 MOhm Impedance Adapter. It was essentially the impedance matching portion of the 41800A, but substituted a female BNC connector for the probe and probe cable. You would use this with your own high-impedance probes (such as those used with oscilloscopes). This product has been discontinued for a few years, however. As with the 41800A, the 41802A received its power from the Probe Power connector on the signal analyzer.
