嗨,我有一台带有效选件1DR键码的E4404B频谱分析仪。
但是分析仪接受的最低RBW是1-kHz,不会低于此值。 视频带宽也不会低于非1DR限制; 它的行为就像选项不存在。 (顺便提一下,该单元没有选项1D5,高稳定时基选项。)我还应该指出,板载内存/时钟电池/晶体似乎已经死了。 无论如何,我做错了什么? 分析仪是否缺少某些内部硬件(非常可能),或者它是否存在严重问题? 思考? 非常感谢! 以上来自于谷歌翻译 以下为原文 Hi, I've got an E4404B spectrum analyzer with a valid Option 1DR keycode. But the lowest RBW that the analyzer will accept is 1-kHz, won't go below that. The video bandwidth also will not go below the non-1DR limit; it acts like the option isn't there. (The unit does not have Option 1D5, High Stability Timebase option, by the way.) I should also point out that the on-board memory/clock battery/crystal appears to be dead. Anyhow, am I doing something wrong? Is the analyzer missing some internal hardware (very possible) or might it have a serious issue? Thoughts? Thanks much! |

你好BigRed,选项1DR的问题在进行升级时更多,但是如果还缺少其他选项,那么可能是因为这个问题在某个时刻失去了它的意义并且已经重建了。
我查看了生产记录,这个仪器最初附带以下选项:1DR - 窄分辨率带宽1DS - 时间门控AYX - 快速时域扫描& IF端口BAA - FM解调后两个要求在仪器卡插槽中安装实际硬件,而其他两个只是启用现有硬件的许可证密钥。 如果您缺少功率套件测量 - 在Meas菜单下 - 您可以重新加载仪器固件,它们将返回。 您是否可以发布系统屏幕,硬件屏幕,许可屏幕的屏幕截图,以确保您实际安装了什么,以便我可以帮助您正确配置它? 麦克风 以上来自于谷歌翻译 以下为原文 Hello BigRed, The issue with the option 1DR is more commen when doing an upgrade, but if other options are also missing it could be that the insturment lost it's mind at one point and it has been rebuilt. I looked at the production records and this instrument originally shipped with the following options: 1DR - Narrow Resolution Bandwidths 1DS - Time Gating AYX - Fast Time Domain Sweeps & IF Ports BAA - FM Demodulation The second two require actual hardware installed in the instrument card slots while the others are just license keys to enable existing hardware. If you are missing the power suite measurements - under the Meas menu - you can just reload the instrument firmware and they will be back. Can you post a screen capture of the System screen, Hardware screen, Licensing screen to be sure what you actually have installed so that I can help you get it configured properly? Mike |
