Hi Alvin.All Ettus Research USRP SDRs ship with default FPGA bitstreams that have the same basic functionality: 1) a digital interface to the RF front end (ADCs/DACs), 2) digital up and down converters, 3) interpolation and decimation blocks to adjust the sample rate, and 4) digital logic for c

Hi Jon. First of all, you should not be using a SG1 image with the E313. All E313s contain E310s with Speed Grade 3 FPGAs. The behavior you describe is a result of a corrupted bit in the AVR EEPROM firmware that results in the power on sequence requiring the power button to be pushed. This corr

Hi Rob. You are specifying use of the RX external LO correctly via device arguments. Each of the daughtercards on the N310 contains a single Analog Device AD9371 2 TX x 2 Rx RF integrated transceiver. The two Tx channels share an LO and the 2 Rx channels share an LO. Consequently, the TX or R
