问题：
I am borrowing the DSA from another group. How can I tell which options are installed?
答案：
With the instrument powered up, look at the second page of the Utility menu. There is a selection labeled Ident. When you select that menu, it will give you the firmware versions in the top part of the menu and any installed options in the lower part of that menu.
