您好,我有一个33250A,我认为可能已经损坏固件,因为它启动,显示“Agilent Technologies 33250A”消息,然后重新启动并重复此循环。
我在Agilent网站上查找了可下载的固件文件,但找不到。 是否可以通过其中一个接口重新加载固件,或者仅通过物理更换闪存ROM才能进行固件更改? 如果是后者,我是否有可能让二进制文件重新刷新我自己的ROM? 或者,有没有办法让我购买预编程的ROM? 谢谢,斯坦 以上来自于谷歌翻译 以下为原文 Hello, I have a 33250A that I think may have corrupted firmware, because it powers up, displays the "Agilent Technologies 33250A" message, then reboots and repeats this cycle. I've looked on the Agilent site for a downloadable firmware file but cannot find one. Is it possible to reload the firmware over one of the interfaces, or is a firmware change possible only by physically replacing the flash ROMs? If the latter, is it possible for me to get the binary files to reflash my own ROMs? Alternatively, is there a way for me to purchase preprogrammed ROMs? Thanks, Stan |

我能够借用一个工作33250A进行一些比较测试。
首先,为了排除电源问题,我将电源从一个交换到另一个。 这两种电源都在借来的仪器中工作,但借来的电源并没有改变我失败的仪器的行为。 然后我*非常小心地在仪器之间交换了四个系统ROM。 这两套都是借来的乐器,但据我所知,借来的套装根本没有改变我乐器的行为。 有趣的是,借来的单元的ROM标记为1.03,但包含1.05版本的固件。 我的仪器的ROM标记为1.03,并具有1.03版本的固件。 我还对主板进行了视觉比较,看看是否有任何明显的差异,但没有看到任何。 关于下一步该尝试的任何想法? 是否有可用于33250A的CLIP? 谢谢! 编辑:swperk于2014年6月28日上午7:05编辑:swperk于2014年6月28日上午8:07 以上来自于谷歌翻译 以下为原文 I was able to borrow a working 33250A to do some comparison testing. First, in order to rule out a power supply problem I swapped the power supplies from one to the other. Both power supplies worked in the borrowed instrument, but the borrowed power supply did not change the behavior of my failing instrument. Then I *very carefully* swapped the four system ROMS between the instruments. Both sets worked in the borrowed instrument, but the borrowed set did not change the behavior of my instrument at all, as far as I could tell. Interestingly, the ROMs from the borrowed unit are marked 1.03 but contain version 1.05 firmware. The ROMs from my instrument are marked 1.03 and have version 1.03 firmware. I also did a visual comparison of the main boards to see if there were any obvious differences, but did not see any. Any ideas on what to try next? Is there a CLIP available for the 33250A? Thanks!
