Summary:In order to validate and demonstrate newly developed ranging techniques, a flexible test platform for signal acquisition enabling offline signal processing is generally needed. Developing such a platform becomes challenging when working with wideband (> 100MHz) signals due to the critical timing, the very high sampling rates and the huge data throughput involved. In this paper, we introduce an Ettus X310 SDR platform using custom designed logic allowing for dual-channel 400 Msps data transmission and acquisition for centimeter level ranging applications. Furthermore, we present initial measurement results as a benchmark of the platform, which show that the time delay of a 10 m cable can be estimated with high accuracy, in the order of 50 ps.
