Please note: As the SDR application runs on an embedded CPU +with limited processing capability, users should leverage the FPGA using tools such as RFNoC to offload compute +intensive algorithms that process high bandwidth samples. The maximum sample rates that can be achieved are 4.4 MS/s on +the E31x and 6.4 MS/s on the E320 when streaming through the RJ-45 port. As the E320 has an additional +highspeed SFP Port, the RJ-45 port should only be used for streaming data from the E320 if necessary. + +The streaming sample rates can be tested and verified using the UHD example benchmark_rate: + + /path/to/benchmark_rate --args addr=<e3xx-ip-address>,master_clock_rate=<master_clock_rate> --rx_rate=<rx_rate> + +To verify maximum streaming rates, the following configuration should be used: +- E310: `master_clock_rate=13.2e6`, `rx_rate=4.4e6` +- E320: `master_clock_rate=19.6e6`, `rx_rate=6.4e6` + \subsection e3xx_getting_started_security Security-related settings The E320 ships without a root password set.
