Dataset: A Comprehensive Analysis of Large‑Scale SDR Synchronisation with the OctoClock‑G

Dataset description: The data is captured using two time- and frequency-synchronised USRP X410 SDRs. To synchronise the two devices, an NI OctoClock-G is used. The transmitter consists of a USRP B210 equipped with a 10 dB attenuator, which transmitted a sine wave generated with the Universal Hardware Driver. This signal is sent through a 1-to-8 RF splitter network to the USRP X410 SDRs.Transmitting a sine wave with UHD: uhd_siggen -a 'serial=your_device_serial' -s 1e6 -f 2412e6 -v -A 'TX/RX' --amplitude=1.0 --sine -g 69.75 uhd_siggen -a 'serial=your_device_serial' -s 1e6 -f 2437e6 -v -A 'TX/RX' --amplitude=1.0 --sine -g 69.75 uhd_siggen -a 'serial=your_device_serial' -s 1e6 -f 2462e6 -v -A 'TX/RX' --amplitude=1.0 --sine -g 69.75 with higher TX gain: uhd_siggen -a 'serial=your_device_serial' -s 1e6 -f 2412e6 -v -A 'TX/RX' --amplitude=1.0 --sine -g 79.75 uhd_siggen -a 'serial=your_device_serial' -s 1e6 -f 2437e6 -v -A 'TX/RX' --amplitude=1.0 --sine -g 79.75 uhd_siggen -a 'serial=your_device_serial' -s 1e6 -f 2462e6 -v -A 'TX/RX' --amplitude=1.0 --sine -g 79.75 Dataset recording settings: Sample rate: 0.96 Msps Bytes to save: 4 (complex short 16) Different Wi-Fi channels: 3 Record time per sample: 1 second Normalised gain settings: 11 Measurements per gain setting: 5 Channels recorded: 8 Different measurements: 3 Total TX/RX0 dataset = 15,21 GB Total RX1 dataset = 15,21 GB Set centre frequencies USRP B210:2412.000000001859 MHz2437.000000001862 MHz2462.0000000018617 MHz
