Hello everyone, [USRP E310] We need to capture some 300 Hz signal for a long period of time (up to 15'), as long as a GPIO is '1'. Minimum configurable bandwith is 286 KHz, what makes us sample the data at 286 KSPS. At this sampling rate, every 15' of capture results in a file of 2.2 GB. The fol

Hi Thomas! The point is that the FPGA image doesn't contain the IP address – that is stored, separately, on the EEPROM. So, as soon as you're in safe mode, use the usrp_burn_mb_eeprom tool that came with UHD (depending on your OS and way of installing, it might be somewhere like /lib64/uhd/utils/

[USRP-users] RFNoC timing clarification

I have a timing question that has me going in circles, I don't understand how the USRP timestamps work when using RFNoC. In a normal system, packets have timestamps with them (or at least the first one does) and you can compute the time of any samples based on the timestamp, sample rate, and n

Hey Jason, The timestamp of each packet describes the time the first sample in the packet was received. The timestamp is based on a counter in noc_block_radio_core (timekeeper.v.) that increments at the sample rate (i.e. radio_clk). The time is relative to that counter's placement in the processin

Howdy Jonathon! Is a "packet" determined before or after the RFNoC stage of the chain (I assume before since it is in the radio core)? Is there anyway to modify things if I decide to resample in an RFNoC block? It seems like it would throw off the timing since the sample rate into the block

The packetization happens in the radio_core (which is in noc_block_radio_core) in a block called rx_control_gen3. That is where the timestamp is applied. The output of that module goes to AXI Wrapper, which doesn't do much since rx_control_gen3 generates the header too. If you want to resample, co
