Hi Dominique - 输入衰减器内部有（3）个内部焊盘部分，总共有70 dB的输入衰减;
10 dB部分，20 dB部分和40 dB部分。
例如，为了实现30 dB的输入衰减，接入20 dB和10 dB部分。由于20 dB，40 dB和60 dB设置似乎正常运行，因此每次显示10 dB部分有缺陷
接通时，存在振幅问题。
输入衰减器部件号（33321-60037）不再可用，因为产品超出支持寿命几年。
安捷伦仍在销售较低级别的部件，如10 dB电路，触点等。
如果您愿意打开输入衰减器，您可能能够找出哪个部件有缺陷。
这可能具有挑战性，因为输入衰减器本身没有示意图。
99％的时间交换机逻辑是正确的，问题的原因是硬件本身。
当10 dB部分出现问题时，通常表示功率过大的情况。
也许可以看到视觉损坏，可以订购和更换适当的下层部件。

Hi Dominique -
There are (3) internal pad sections inside the input attenuator that make up a total of 70 dB of input attenuation; a 10 dB section, 20 dB section and 40 dB section. To achieve 30 dB of input attenuation for example, the 20 dB and 10 dB sections are switched in. Since the 20 dB, 40 dB and 60 dB settings appear to be operating correctly, it appears the 10 dB section is defective because every time that is switched in, there is an amplitude problem.
The input attenuator part number (33321-60037) is no longer available as the product is several years beyond the support life. Lower level parts such as the 10 dB circuit, contacts, etc. are still sold by Agilent. If you’re willing to open up the input attenuator, you may be able to find out which part is defective. This may be challenging as there are no schematic diagrams for the input attenuator itself. 99% of the time the switch logic is correct and the cause of the problem is the hardware itself. When the 10 dB section has a problem it is usually indicative of an over power situation. Perhaps visual damage can be seen and appropriate lower level parts can be ordered and replaced.
