By "source" one should undetstand a source of samples for the outside of SDRangel application. An UDP connection is established from the plugin to the given address and port and samples are directed to it.

An UDP connection is established from the plugin to the given address and port and samples are directed to it.
The UDP block size or UDP payload size is fixed to 512 samples. The size in bytes depends on the format: The UDP block size or UDP payload size is fixed at 512 bytes.
- S16LE types not labeled as "mono": each sample is a complex sample of two 16 bit signed integers therefore the block size is 2048 bytes The receiving application must make sure it acknowledges this block size. UDP may fragment the block but there will be a point when the last UDP block will fill up a complete block of this amount of bytes. In particular in GNUradio the UDP source block must be configured with a 512 bytes payload size.
- S16LE types labeled as "mono": each sample is a real sample of a single 16 bit signed integer therefore the block size is 1024 bytes
