感谢上一个问题的帮助,但现在有一个不同的问题。 E8257D是一个选项550,当软件试图运行高频段调整时,它会失败。我注意到,当它经过-3dBm测试时,它运行得非常快,功率计会在较高的频率下急剧下降(通常在30或-10GHz之间的-10或-11dB之间下降),但是当接下来的测试时( - 运行13dBm和-18dBm,它们慢得多并且没有明显的下降。我手工操作类似的东西,并没有看到任何严重的下降。正在使用的设备切换,我一直使用8487A功率传感器,但我在E4419B和N1914A功率计之间切换(两个仪表都有相同的问题)。 以上来自于谷歌翻译 以下为原文Thanks for the help with the previous problem, but now there is a different problem. The E8257D is an option 550 and when the software tries to run the high band adjustment it fails. I've noticed that when it runs through the -3dBm test it runs very quickly and the power meter will drop dramatically in the higher frequencies (usually a drop between -10 or -11dB above 30GHz), but when the next to tests (-13dBm and -18dBm) run, they are much slower and show no significant drops. I've run something similar by hand and have not seen any drops that badly. The equipment being used switches up, I consistently use the 8487A power sensor, but I switch between the E4419B and the N1914A power meters (same problems with both meters).
