Function

Allows you to reverse the last screen scaling or offset operation performed on a selected channel. When “undone”, the waveform will revert back to the original values before the previous scaling or offset operation. Note that this feature only works on the same channel as the most recent scaling or offset operation. Subsequent undo operations toggles the waveform back and forth between the previous and most recent versions of screen scaling or offset.

Activating Procedure

A scaling or offset operation must be performed on a selected channel to make the Undo command selectable (undimmed). Once Undo becomes selectable, you can perform any other operation (except another scaling or offset operation) on any other channel and still have the capability to come back to the selected channel and undo the last screen scaling or offset operation.

After scaling or offsetting a waveform, reverse the operation as follows:

  In the Edit menu click on Undo.

   Choose Edit Undo (ALT, E, U).

Example
