测量电相时误差为+/- 20度

问答对人有帮助，内容完整，我也想知道答案 0 我公司目前有8个N9912A用于维护和排除天线故障。我们有两个Agilent Fieldfox，其余的是Keysight Branded Fieldfoxes。我的问题始于新的Keysight设备。当测量在VVM模式下执行S21测量时，信号通过天线耦合，我的Keysight设备上的读数报告与旧的Agilent型号相差+/- 20度。我们对这些天线有一套已知的公差，Keysight的读数超出了这个范围。在我应该注意的两个模型之间是否有任何设置或更改？谢谢，Mnolting 以上来自于谷歌翻译以下为原文 My company currently has eight N9912A's that we use for maintaining and troubleshooting antennas. We have two Agilent Fieldfoxes and the rest are Keysight Branded Fieldfoxes. My problems started with the new Keysight equipment. When measuring performing a S21 measurement in VVM mode where the signal is coupled through an antenna, the readings on my Keysight equipment report a +/- 20 degree difference from the older Agilent models. We have a set of known tolerances for these antennas and the readings from the Keysights fall outside this range. Is there any settings or changes between the two models I should be aware of? Thanks, Mnolting 0

答案对人有帮助，有参考价值 0 嗨，安捷伦到Keysight的内部硬件没有变化，只是前面板标签。您拥有的各种FieldFox可能会加载不同的固件。我的建议是检查固件状态并使用最新版本A.08.10进行更新。如果它们都具有最新的并且仍然针对相同的测量产生不同的结果，我们可以开始对该问题进行故障排除。 [系统] {服务诊断} {系统信息}将显示您当前拥有的固件版本。以下是获取最新信息的链接：http：//www.keysight.com/main/editorial.jspx？cc = US＆amp; cs = eng＆amp; ckey = 2639018＆amp; nid = -32495.1150124＆amp; id = 2639018另请注意， VVM模式，期望您将测量归零。此致，Afsi 以上来自于谷歌翻译以下为原文 Hi, There was no change in internal hardware from Agilent to Keysight, simply the front panel label. It is possible that the various FieldFoxes you have are loaded with different firmware. My recommendation is to check the firmware status and have them updated with the latest, which is A.08.10. If they all have the latest and still produce different results for the same measurements, we can start troubleshooting the issue. [System] {Service Diagnostics} {System Information} will show you the Firmware Release that you currently have. Here is the link to get the latest: http://www.keysight.com/main/editorial.jspx?cc=US&lc=eng&ckey=2639018&nid=-32495.1150124&id=2639018 Also note that in VVM mode, there is an expectation that you zero the measurement.
