24 Complete List of Channel Types
The following sections show channel types (applications) and associated measurements supported
by the VC-8000.
• Default measurements are included automatically when the channel is added. Measurements
included by default can be deleted. See section 16.1.11.
• Some measurements can be added (if needed). See section 16.1.10.
• Required PT measurements require a Phase Trigger to function.
