Next Generation VLBI System (Hitoshi Kiuchi)

In developing new VLBI data acquisition system for astronomical applications, it is the most important to take into consideration the requirement of the multi-bit sampling, the high-speed (wide-band) data sampling. We are developing a new sampling system for K-4 data recorder: its sampling rate is increased to 2 (or 4) Gsps, 8-bit quantization. The block diagram is shown in Fig.7. We are developing a real time VLBI system for the KSP system, which is shown in Fig.8.
