Аннотация

The design of a new FX software correlator intended for the new small antenna VLBI network was started at IAA RAS in 2012. The main principles, topology, hardware, and software solutions for the design of a six-station, near-real-time correlator with the ability to process 16 Gbps data are presented. Benchmark test results are given. First fringes with wideband observations were obtained.
