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.
