任何人都可以了解上述主题:我们有一个E4403B频谱分析仪,我们只在顶行的按钮上进行屏幕更改。
按下其中一个按钮后,屏幕将切换到该菜单,但您无法再手动进行更改。 所有其他按钮按钮都不起作用。 可以通过GPIB和软件更改单元HOWEVER。 看来该单元进入远程模式一些如何并被卡住。 我们已经关闭了电源,拔下电源线等一天,但无济于事。 几乎就像一个位置写在内存中。 史蒂夫 以上来自于谷歌翻译 以下为原文 Can anyone shed light on above subject: We have an E4403B Spectrum Analyzer and we only get screen changes on the top row of buttons. Once you push one of these buttons the screen changes to that menu but you can no longer make changes manually. All other button pushes do not work. The unit HOWEVER can be changed via the GPIB and software. It appears that the unit got into a remote mode some how and is stuck. We have powered the unit down, pulled power cord, etc. for a day BUT no avail. Almost like a location was written to in memory. Thx Steve |

嗨,史蒂夫 - 电源循环后,仪器将处于本地模式,这意味着所有前面板硬键和软键应完全正常工作。
它只是软键的底行不工作,还是有一些前面板硬键不能正常工作? 您可以按System,More,Diagnostics(如果它们工作)并执行前面板测试以获取不可操作的键列表。 CPU将前面板按键解释为行/列类型的矩阵或格式的中断。 例如,第3行第4列是显示特定菜单的特定键。 键的描述将根据乐器所处的模式或测量特性而改变。底线是听起来像前面板键盘或者可能需要更换柔性电路。 问候 - 以上来自于谷歌翻译 以下为原文 Hi Steve - After a power cycle the instrument will be in Local mode, meaning all front panel hardkeys and softkeys should be fully functional. Is it just the bottom row of the softkeys that are not working, or are there some front panel hardkeys that are not functional as well? You can press the System, More, Diagnostics keys (if they work) and perform the Front Panel Test to get a list of keys that are not operational. The CPU interprets the front panel key press as an interrupt to a row/column type of matrix or format. For example, row 3 column 4 is a specific key that brings up a specific menu. Key descriptions will change based on the mode or measurement personality that the instrument is in. The bottom line is it sounds like your front panel keypad or perhaps the flex circuit needs to be replaced. Regards - |
