Development of a New VLBI Sampler Unit (K5/VSSP32) Equipped with a USB 2.0 Interface

چکیده
National Institute of Information and Communications Technology (NICT) has developed a new VLBI sampler unit named K5/VSSP32 dedicated to e-VLBI which is a successor to the K5/VSSP. The maximum sampling frequency per channel of the K5/VSSP32 is 64 MHz, which is four times as fast as that of K5/VSSP. In addition to the maximum sampling frequency, there is a difference in the interface to a host PC. A USB 2.0 (Universal Serial Bus specification revision 2.0) interface is used to connect the sampler with a host PC in the K5/VSSP32, while a PCI-bus interface is in the K5/VSSP. It is hence possible to use even a notebook PC for VLBI observations with the K5/VSSP32.
