uff.receive_setup< uff
Describes the setup used to receive and sample data. If more than one probe is used in reception, this is a list of setups.
Parameters
| Parameter | Datatype | Description |
|---|---|---|
| probe | uint32 | Index of the uff.probe used in reception within the list of probes in the uff.channel_data structure |
| time_offset | single or double | Time delay between the event start and the acquisition of the first sample [s] |
| channel_mapping | Matrix of uint32 | Map of receive channels to transducer elements |
| sampling_frequency | single or double | Sampling frequency of the recorded channel data [Hz] |
| tgc_profile | array of single or double | (Optional) Analog TGC profile sampled at tgc_sampling_frequency [dB] |
| tgc_sampling_frequency | single or double | (Optional) Sampling frequency of the TGC profile [Hz] |
| modulation_frequency | single or double | (Optional) Modulation frequency used in case of IQ-data [Hz] |
Notes
The channel_mapping specifies 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 0.
