Dear All, We are working on prototyping Signal Processing Algorithms for Radar and localization scenarios (wideband signals). At the moment we are setting up the testbed for testing our algorithms. We are interested in the streaming and storing of high data rate samples full bandwidth of 2x 160 MHz UBX cards to the file in PC. Later on, we would perform offline processing of those samples.
We managed to find several posts related to the similar work. However, we did not manage to find concrete suggestions or reference guideline how to setup system that is able to perform offline acquisition of full bandwidth signals supported by 2xUBX-160 cards in PC. Our questions is directed to Ettus Research developers and anyone who was trying to achieve same: 1. What is hardware configuration for the PC in order to support streaming and storing of samples from 2xUBX-160 cards (2(cards)x2(IQ)x160(BW)x8(sample size)) to SSD memory? 2. Did you in Ettus tried to do a similar experiment and could you provide us references for HW and SW configurations? Our testbed at the moment consists of: 1. PC (Dell Precision Tower 5810 - https://www.dell.com/en-ca/work/shop/dell-desktops-workstations/dell-precision-tower-5810-workstation-build-your-own/spd/precision-t5810-workstation/cup5810onca): RAM: 4x4GB (https://www.micron.com/parts/modules/ddr4-sdram/mta9asf51272pz-2g3) (This we could also extend to 32GB or 64GB) CPU: Intel Xeon - Intel Xeon Processor E5-1620 v3 (4C, 3.5GHz, Turbo, HT, 10M, 140W) SSD: skhynix 512GB, 2.5'', Read : up to 550MB/s, Write : up to 480MB/s. (http://ssd.skhynix.com/ssd/en/about/sc300a.jsp) (this we plan to extend and maybe change as writing speed is low and capacity is low. Do you have a recommendation for SSD configuration ?) 2. USRP X310 RF DaugtherBoard: 2x UBX-160MHz PC-USRP interface: 2x10GB ethernet interface Thank you in advance on comments and suggestions, Tarik
