All function groups and test modes available on the instrument are arranged in a tree view. When the popup is opened, this configuration tree is expanded and the active function group and test mode is selected.
Nodes containing subnodes (e.g. function groups containing the test modes Non Signalling and Signalling) are marked with rectangular symbols, lowest-level nodes (e.g. the individual test modes within a function group) with smaller, quadratic symbols:
 |
The node is deselected |
 |
The node is partially selected, i.e. some but not all of the subnodes are selected |
 |
The entire node is selected, i.e. all of the subnodes are selected |
The controls in the Reset window are manipulated with the roll-key, the cursor keys and the ENTER key:
  |
Toggle between the Cancel and the Reset buttons |
  |
Toggle between the control buttons (Cancel, Reset) and the tree view |
| Roll-key | Toggles between the Cancel and the Reset buttons (when turned) or activates a button (when pressed). In the tree view, the roll-key moves the control frame up and down (when turned) or expands/compresses a node (when pressed). Pressing the roll-key on a lowest-level node selects or deselects the node. |
| ENTER | Activates a button or selects/deselects a node including all subnodes. |
