VITA49 PSD Packetizer¶

Overview¶

Generate VITA 49.2 spectral data packets from incoming data.

Description¶

This operator will take in PSD data computed by upstream operators and format it into VITA 49.2 Spectral Data packets.

After creating the VRT packets, it will send the packets to the configured UDP IP/port.

[!NOTE] This operator pulls in projects that contain LGPL-3.0 code.

Requirements¶

MatX (dependency)
vrtgen (dependency, LGPL-3.0)
vita49-psd (dependency, LGPL-3.0)

Multiple Channels¶

If multiple channels are configured, the packetizer will use the base port in the configuration and add the channel index. So, with base_dest_port: 4991, channel 0 would send data to 4991, but channel 1 would send data to 4992.

The zero-indexed channel_number key will be looked up in metadata() on each compute() run. If no value is found, the default channel number is 0.

Example Usage¶

For an example of how to use this operator, see the psd_pipeline application.

Configuration¶

The packetizer takes the following parameters:

vita49_psd_packetizer:
  burst_size: 1280
  num_channels: 1
  dest_host: 127.0.0.1
  base_dest_port: 4991
  manufacturer_oui: 0xFF5646
  device_code: 0x80

burst_size: Number of samples to process in each burst
num_channels: Number of channels for which to allocate memory
dest_host: Destination host
base_dest_port: Base destination UDP port
manufacturer_oui: Manufacturer identifier to embed in the context packets
device_code: Device code to embed in the context packets
