Make the selected slot a width-reference. You will be prompted to give it a name. The default name consists of the text “TauMaster1”. You may change the name later using RENAME MASTER hierarchical menu.
The color of the pulse changes to red.
The same restrictions apply to “master” slots as to “master” pulses - you may not delete, cut, clear or paste over them. For work around see the [ TIMING ] PROMOTE TO MASTER command. You may DUPLICATE or COPY / PASTE them and the copied pulse will automatically become its “slave” equal in size.
