uff.transmit_setup< uff
UFF class to describe the transmit event (probe/channels, waves, excitations, etc.).
Parameters
| Parameter | Datatype | Description |
|---|---|---|
| probe | uint16 | Index of the uff.probe used for transmit within the list of probes in the uff.channel_data structure |
| transmit_waves | uff.transmit_wave | List of transmit waves used in this event with their respective time offset and weight |
| channel_mapping | uint16 | Map of transmit channels to transducer elements |
| sampled_delays | single or double | (Optional) Transmit delay line as set in the system for active channels [s]. |
| sampled_excitations | single or double | (Optional) Matrix of sampled excitation waveforms [normalized units]. |
| sampling_frequency | single or double | (Optional) Sampling frequency of the excitation waveforms [Hz] |
| transmit_voltage | single or double | (Optional) Peak amplitude of the pulse generator [V] |
Notes
The object transmit_setup contains a reference to the probe used to transmit the waves, an array describing all the transmit_waves, and a channel_mapping dataset describing the connection of system channels to transducer elements. The map is a M-by-N matrix (HDF5 dimension ordering), where N is the number of system channels and M is the maximum number of elements connected to a single channel. In most common cases, M=1. An unconnected state is marked by the value -1.
