Meta TEDS

The Meta TEDS is a mandatory TEDS. Its function is to provide all the necessary information at the interface to access any TransducerChannel, along with details that are shared across all TransducerChannels.

info

The Meta TEDS is defined in the 6.4 Meta TEDS. Check this IEEE 1451.0-2024.
