Shipping UniRacks for AAVS
| Submitter: | Gijs Schoonderbeek |
| Description: | The image shows Sjouke Zwier shipping a UniRack (rack of UniBoards) to the University of Cambridge (UK). By the time of publication of this daily image another rack will have been sent to the International Centre for Radio Astronomy Research (ICRAR) in Perth (Australia). The subrack consists of two UniBoards, four ADUs (Analog to Digital conversion Unit) and a PAC (Power And Clock distribution) board. The system will be used for AAVS (Aperture Array Verification System) in the LFAA (Low Frequency Aperture Array) SKA consortium. For this application, the WSRT/APERTIF beamforming firmware was re-used and modified to a beamformer for 16 antennas, with a bandwidth of 300MHz, on a single UniBoard. |
