无法在MSO-X-3000上选择Expand-Ground选项

由于某种原因，“展开关于”的“地面”选项显示为灰色，因此无法选择。
将仪器重置为“出厂默认值”会使选项返回，但一旦我回想起我的设置就会消失。
我尝试将expandMode *从* 1，“center”*更改为* 0，“ground” - 但它没有任何效果。
我正在运行2.38并且在两个范围上遇到同样的问题。
谢谢。

  For some reason "Ground" option for an "Expand About" is grayed out and hence not selectable. Resetting the instrument to "Factory Default" brings the option back but disappears once I recall my setup. I tried changing expandMode *from* 1,"center" *to* 0,"ground" - but it had no effect.

I'm running 2.38 and have the same problem on two scopes.

Thanks.
