Make the selected pulse an amplitude reference - a “master”. You will be prompted to give it a name. The default name is “AmplMaster1”. You may change the name later using RENAME MASTER >> hierarchical menu.
The color of the pulse changes to red.
Some restrictions apply to “master” pulses - you may not delete, cut, clear or paste over them. For work-around see PROMOTE TO MASTER command below.You may copy a “master” and the copied pulse will automatically become its “slave” equal in size.
