Signal Labels on Waveform Content Window

Normal Channel Labels	Default Port Labels	Custom User Labels

To display the default port or custom user label, use the :TDR:ASNaming command. User labels (names) are helpful because they identify what a waveform represents rather than the input channel. For example, you could assign a user name "DUT Gain".
