我最近购买了一个固件版本为7.05的E4406A，s / n US3903xxxx，它工作正常，没有错误的自拍，没有问题的自动对齐，并且应该正常工作。
由于最新的固件是10.08，我决定升级该仪器的固件。
但是，当我尝试升级时，我注意到在升级的最后，状态消息说有几个文件无法创建。
即便如此，升级后屏幕上的最后一条消息是升级完成后我应重启并重新启动仪器。
当我重新启动仪器时，我正在看启动屏幕，发现了一个我以前从未见过的消息。
它说：vsa vsa：糟糕的价值，但继续启动。
最终我听到衰减器继电器发出咔嗒声，在它开始自我测试之前它就到了空白的白色屏幕。
但它没有到达那里，并在屏幕上显示以下消息：users / arcturus / .xinitrc：57内存故障固件退出，循环
电源重新启动产生相同的结果。
我还尝试使用安装程序中的“非功能性仪器”选项安装固件版本8.10第2版，但获得的结果与10.08固件相同。
最后，我再次使用“非功能性仪器”选项恢复到7.05固件，我的E4406A恢复正常工作。
有谁知道这可能导致什么？
7.05和更高版本之间的固件是否有重大变化可能解释这种不兼容性？
接下来要检查什么的想法？
我有另一台E4406A我已成功升级到10.08，所以我非常有信心我知道这个程序，但是任何和所有的建议都会受到赞赏。

以下为原文
I recently acquired an E4406A with firmware version 7.05, s/n US3903xxxx, and it works fine, booo
ting without errors, self-aligning without a problem, and working as it should.
Since the latest firmware is 10.08, I decided to upgrade the firmware in this instrument. However, when I tried to upgrade, I noticed that at the very end of the upgrade, the status messages said that there were several files that it was unable to create. Even so, the final message on the screen after the upgrade was that the upgrade was complete and I should power cycle and reboot the instrument.
When I restarted the instrument, I was watching the boot screen and noticed a messsage that I hadn't seen before. It said:
vsa
vsa: bad value
but continued to boot. Eventually I heard the attenuator relays click, and it got to the blank white screen just before it would have started the self-testing. It didn't get there, though, and stopped with the following message on the screen:
users/arcturus/.xinitrc: 57 memory fault
Firmware exit, cycle power
Restarting produced the same results. I also tried installing firmware version 8.10 Release 2 by using the "non-functional instrument" option on the installer, but got the identical results as with the 10.08 firmware. Finally, I reverted back to the 7.05 firmware, again by using the "non-functional instrument" option, and my E4406A is back to working fine.
Does anyone know what might be causing this? Was there a significant change in firmware between 7.05 and the later versions that might explain this incompatibility? Any ideas of what to check next? I have another E4406A that I have sucessfully upgraded to 10.08, so I'm pretty confident that I know the procedure, but any and all suggestions would be appreciated.
Thanks,
Stan
