HP 8563E问题错误459 561 562 564 565

您好jamesmliu，来自服务指南[http://sa.support.keysight.com/8560/Service/Manuals/08563-90214.pdf]我可以看到您的错误的描述符：_Automatic I.F.
错误：_ 459 AMPL无法调整第一步增益阶段561 LOG AMPL无法调整对数刻度的幅度。
可能是第二步增益562 LOG AMPL无法调整对数刻度的幅度。
可能是第二步增益564 LOG AMPL无法调整对数刻度的幅度565 LOG AMPL无法调整对数刻度的幅度因此，您的单位似乎与对数放大器（A4组件的一部分）有故障。
虽然这是一个较旧的型号，但我建议您将设备送到最近的Keysight客户服务中心进行免费技术评估，因为有几个旧的服务说明可能适用于您的设备。
我希望这会有所帮助，干杯，Simon C.编辑：simon_coleby于2015年5月21日上午10:04编辑：simon_coleby于2015年5月21日上午10:15

  Hi jamesmliu,

From the Service Guide [http://sa.support.keysight.com/8560/Service/Manuals/08563-90214.pdf] I can see the descriptors for your errors:

  _Automatic I.F. errors:_

  459   AMPL           Unable to adjust 1st Step gain stage
  561   LOG AMPL   Unable to adjust  amplitude of Log scale. Possibly 2nd Step Gain
  562   LOG AMPL   Unable to adjust  amplitude of Log scale. Possibly 2nd Step Gain
  564   LOG AMPL   Unable to adjust  amplitude of Log scale
  565   LOG AMPL   Unable to adjust  amplitude of Log scale 

So it seems like your unit has a fault with the Logarithmic Amplifier, part of the A4 assembly.
Although this is an older model, I would recommend sending your unit to your nearest Keysight Customer Service Center for a free technical evaluation, as there are several old Service Notes that may apply to your unit.

I hope this helps, 
Cheers, Simon C.

嗨Simon C，谢谢回复。
我有来自E-Bay的HP 8563A和hp8563E CLIP。
所以我尝试修复A4组件的Logarithmic Amplifie部分。
似乎U201和U501 CA3127E晶体管阵列可能出现故障。
再次感谢。
干杯，詹姆斯刘

  Hi Simon C,

Thank you respond.
I have a HP 8563A and hp8563E CLIP from E-Bay.
So I try to repair the Logarithmic Amplifie part of the A4 assembly.
It seems probable U201 and U501 CA3127E transistor array fail.

Thanks again.
Cheers,  James Liu
