2019 DPM RSSI Output

This page describes the data format as received by software from the Packetizer/RSSI/UDP core.

The frame received by software will contain a series of trigger frames as output from the Firmware Event Builder. The number of event builder frames will be determined by the configured block size. 

These frames will be formed into a larger frame using the SLAC Stream Batcher protocol.
