强度控制不适用于DSO6104A

另外几个观察结果：1）当我通过门户网站访问DSO6104A时，我可以通过Web界面控制范围的强度。
当我调整计算机的强度时，“速度表”刻度盘会显示在示波器的显示屏上。
2）我注意到门户网站将范围标识为DSO6104L，而不是DSO6104A。
是否有可能因为它仍然认为它是L版本，它已禁用板载硬件强度控制？
此时，我能想到的唯一另一种可能性是硬件旋转编码器或其相关电路的故障。
我只能通过使用运行WinXP和旧版Java的笔记本电脑来访问示波器。
在我的Win8.1 PC上运行的最新版本的Java具有比以前更高的安全级别，因此现在要求我输入作用域的IP地址作为安全例外，以允许远程前面板应用程序在浏览器中运行
。
虽然我已将IP地址作为例外输入，但Java仍然会出现此消息：java.security.AccessControlException：access denied（“java.net.SocketPermission”“192.168.1.61:5900”“connect，resolve”）。
我不是想象力的Java专家，所以我希望有人能指出我正确的方向来解决这个问题。
谢谢和节日快乐，StanEdited：swperk于2014年12月24日10:01 AM



     以下为原文

  A couple of additional observations:

1) When I access the DSO6104A through the web portal, I can control the intensity on the scope through the web interface. The "speedometer" dial shows up on the scope's display as I adjust the intensity on the computer. 

2) I notice that the web portal identifies the scope as a DSO6104L, instead of a DSO6104A. Is it possible that because it still thinks it's an L version, it has disabled the onboard hardware intensity control? 

At this point, the only other possibility I can think of is a failure of the hardware rotary encoder or its associated circuitry.

I was able to access the scope only by using a laptop running WinXP and an older version of Java. The latest version of Java that is running on my Win8.1 PC has higher security levels than before, so it now requires me to enter the IP address of the scope as a security exception to allow the remote front panel app to run in the browser. Although I have entered the IP address as an exception, Java still errors with this message: java.security.AccessControlException: access denied ("java.net.SocketPermission" "192.168.1.61:5900" "connect,resolve"). I'm by no stretch of the imagination a Java expert so I hope someone can point me in the right direction to fix this issue as well.

Thanks and Happy Holidays,
Stan

我与MSO1704A有相同的Java问题。
即使添加了IP地址的例外，它也不会运行远程前面板，有和没有：5900。
错误是：java.security.AccessControlException：访问被拒绝（“java.net.SocketPermission”“10.178.188.178：5900”“connect，resolve”）编辑：David F于2015年1月5日下午12:58



     以下为原文

  I'm having the same Java problem with a MSO1704A.  It won't run the remote front panel, even after adding exceptions for the IP address, with and without :5900.  Error is:   java.security.AccessControlException: access denied ("java.net.SocketPermission" "10.178.188.178:5900" "connect,resolve")

这不是问题的解决方案，但一种解决方法是使用VNC客户端（例如UltraVNC或RealVNC）并直接连接到IP而无需Java。



     以下为原文

  This is not a solution to the questions, but one workaround is to use a VNC client (such as UltraVNC or RealVNC) and connect directly to the IP without needing Java.

这仅适用于软菜单按钮，软件不提供对实际用户界面的控制。



     以下为原文

  This only works for the soft menu buttons, the software does not offer control of the actual user interface.

在MSO 6104A闲置几年之后我就把它拿出来了。
它向右发射，令我惊讶的是，时间和日期相当准确。
我打开它再看一下强度控制，我注意到控制体内出现了一些油腻的残留物。
我用接触式清洁剂喷洒它，将一堆硬化的润滑剂从身体中冲洗干净，然后将它们全部放回原处。
控件现在可以正常工作，因此问题原来是一个有缺陷/脏的编码器。



     以下为原文

  I got out the MSO 6104A after it had been sitting unused for a couple of years. It fired right up, and much to my amazement, the time and date were fairly accurate. I opened it up to have one more look at the intensity control and I noticed that there appeared to be some greasy residue coming out of the body of the control. I sprayed it with contact cleaner, flushed a bunch of hardened lubricant out of the body, and put it all back together. The control now works as it should, so the problem turned out to be a defective/dirty encoder.
