The level of detail parameter determines which submodules of the transmitter will be used:

Level (domain)	Submodules
PACKET	-
BIT	signal encoder, data encoder
SYMBOL	signal modulator, data modulator + bit level modules
SAMPLE	pulse shaper + bit, symbol level modules + (digital/analog converter)

Important: We have no default module implementation for sample level features.

Note that if a digital/analog converter is provided for the transmitter then it will be only used at sample level, otherwise, since analog representation is obligatory, a simplified, built-in (scalar) analog model is used at all levels.

Note that in non-compliant mode, whatever the level of detail is, you must always set all submodules. If the current level of detail does not demand a specific submodule it is necessary and sufficient to implement those methods of that submodule which provide metadata about its settings.

For example, if the level of detail is bit level, you don't have to implement a complete modulator, it is enough to implement a dummy modulator that can give information about its subcarrier modulation (e.g. BPSK).
