安捷伦DSO5012A被冻结

你好。
我应该从修理DSO5012A开始的任何建议 - 它会偶尔停止，所有键都被冻结，显示屏显示垂直线条。
多次上电后，示波器已恢复，并显示错误消息“由于发生软件错误，示波器默认显示。
请报告以下诊断信息。
PC板/状态A / D问题。“冻结通常在示波器通电时发生。
在测量会话中也发生了几次。
它还给出了一次错误“示波器默认是因为发生了软件错误。
请报告以下诊断信息。
内华达125MHz时钟未运行“所有建议都非常感谢。
BR，Jaakko

  Hi. Any advice where I should start with repairing my DSO5012A – it occasionally halts with all keys frozen and the display is showing vertical lines. After powering on several times the scope has recovered giving an error message “The oscilloscope is defaulted because a software error occurred. Please report the following diagnostic information.  
PC-board/Status A/D problem.”
The freeze happens typically right when the scope is powered on. It has also happened a couple of times in the middle of a measurement session.
It has also given once an error “The oscilloscope is defaulted because a software error occurred. Please report the following diagnostic information.  
Nevada 125MHz clock not running”
All advice is highly appreciated.
BR, Jaakko
