我们在盒子里没有找到你们寄给我们的新衰减器。在找到新的衰减器后我们进行了更换。更换后EESI信号NaINa等出现了并表现出波动性。然而这些信号在几分钟后消失了。请参见附件。在整个过程中我们没有进行任何操作。英文

We were unable to find the new attenuator you had sent us in the box. Once we located the new attenuator, we proceeded with the replacement. After the replacement, EESI signals (NaINa, etc.) appeared and exhibited some fluctuations. However, these signals disappeared after a few minutes. Please refer to the attached file. We did not perform any operations during the entire process.
