CLBv2 Shore Station

The testing of the Shore Station Demonstrator at IFIC Valencia showcased successful data broadcasting using SPEC cards and CLB technology. The first test involved two SPEC cards, achieving sub-nanosecond accuracy. Subsequent tests with three SPEC cards confirmed performance while exhibiting successful calibration. All three broadcasting tests were completed successfully, verifying capabilities with both a CLB and the advanced SPEC cards. Future steps include building a new shore station demonstrator in Athens, with additional equipment preparation underway.

  2. Testing the Shore Station Demonstrator at IFIC Valencia • Shore station demonstrator • 3 level network topology (3 White Rabbit switches) • 3SPEC cards, 1 CLBv2 • exact replica of the shore station demonstrator test setup, that 7Solution has created at Granada • Participants: Diego Real, Emilio Marin Lopez (7S), Belias Tassos, Kostas Manolopoulos

  3. 1st Data Broadcasting Test • Data Broadcasting with 2 SPEC cards

  4. 1st Test Results before calibration • Green line: 1st SPEC card • Yellow line: 2nd SPEC card • Red line: WR Broadcasting switch • Blue line: Level_1 WR switch Skew is observed before the calibration

  5. 1st Test Results after calibration • Test was successful and sub-nanosecond accuracy was achieved!

  6. 2nd Data Broadcasting Test • Data Broadcasting with 3 SPEC card (for the very first time!)

  7. 2nd Test Results after calibration • Red line: WR Broadcasting switch • Blue, green, yellow line: SPEC cards 1, 2, 3 • Testing the data broadcasting with 3 SPEC cards was a success!! • Achieved sub-nanosecond accuracy

  8. 2nd Test Results overnight results

  9. 2nd Test Results overnight results

  10. 3rd Data Broadcasting Test • Data Broadcasting with 1 SPEC card and 1 CLB

  11. 3rd Test Results before calibration • Green line: CLB • Yellow line: SPEC card • Red line: WR Broadcasting switch • Blue line: Level_1 WR switch

  12. 3rd Test Results after calibration

  13. Summary • All 3 tests were successful • Verified data broadcasting with 3 SPEC cards • Verified data broadcasting using a CLB • IFIC has an operational shore station demonstrator • Nest steps • Building a shore station demonstrator in Athens • Received WR starting kit + WR switch • Ready to order a second WR switch • At some point a couple of CLBs will be needed
