如何自定义此示波器图片？

这是我从中复制粘贴的示波器图片texample.net 我稍微修改了代码，现在我遇到两个问题：

  • 我想画一些连接到示波器的通道 1、通道 2 和接地端子的探头。
  • 我不知道如何设置右下面板上的伏特/格旋钮。我想单独设置它们。您可以查看我下面发布的 MWE。

有人可以帮我做这些吗？

答案2

一个问题的答案...如何改变旋钮的角度位置。

寻找评论

% Volt/div foreach 循环绘制两个按钮。

\foreach 循环迭代两个旋钮。项 {18/75,22.5/345} 是旋钮设置的移位位置 \i 和角度 \b。要更改角度，请更改第二个值。例如...

\foreach \i / \b in {18/75,22.5/180}

... 将设置第二个旋钮指向正左方向。

要更改每个旋钮的文本，请进行此更改并观察结果

  \foreach \i / \b / \c in {18/75/bla,22.5/180/foo}{
  %Second parameter of the loop is the angle of the index mark 
  \begin{scope}[xshift=\i cm,yshift=3.8cm,scale=0.85]
    \node[scale=\scl] at (0,2.3) {\c};
