嗨Charles，您可以在仪器之间交换内存，但是在它工作之前您需要重新加载仪器固件。
固件和其他文件保存在仪器闪存中，该闪存位于两个不同的位置。
所有仪器中的CPU板都有4M的闪存焊接，它是不同的存储板。
它们具有4M或12M的闪光（12M是选项B72）。
因此，当您通过移动内存板来交换内存时，您将不会全部移动内存，因此它将无法工作，您需要执行固件加载以将其全部整理出来。
在加载固件之前，最好在移动后清除内存。
另外，请务必同时转移闪存板和DRAM内存板，不要将B72和非B72板混合在仪器中。
还有一件事。
如果您在E4404B中有任何许可证密钥，则需要在交换内存之前将其复制下来，因为它们也保存在闪存中。
因此，在交换后重新加载它们之前，你不会拥有它们。

Hi Charles,
You can swap the memory between the instruments but you will need to reload the instrument firmware before it will work.
The firmware and other files are kept in the instrument flash memory, which is in two different places. The CPU board in all instruments has 4M of flash memory soldered onto it, it's the memory boards that are different. They have either 4M or 12M of flash (12M being option B72). So when you swap the memory by moving the memory boards you won't be moving it all, so it will not work, you need to do a firmware load to straighten it all out. It would probably be best to clear the memory after moving it, before loading the firmware.
Also, be sure to transfer both the flash memory board and the DRAM memory board, don't mix the B72 and non-B72 boards in an instrument.
One other thing. If you have any license keys in the E4404B you will want to copy them down before swapping the memory, as they are also kept in flash. So you won't have them until you reload them after the swap. (System, More, More, Licensing)
Best regards,
