|Description:|| TADU, the Tied Array Distribution Unit and the missing link between the DZB and Mark5B recorder is now operational. The pictures show the input and the output sides of the system.|
During the October VLBI session, TADU became fully operational. This ends a seven years period of designing, building and programming.
In October 2002 the design of TADU started, originally intended for a system with analog outputs for the Mark4B recorder. In October 2003 the design changed to a digital solution, with VSI_H compatible outputs for the Mark5B recorder. Now TADU distributes the 32 outputs from the DZB-TAAM boards to 16 channels of the Mark5B recorder and 16 outputs to PUMA. For the Mark5B the data will be filtered by an 128-taps FIR filter, selectable from 16 MHz to 0.25 MHz. For PUMA, the data is unfiltered.
