2LAT System Engineering ACD Early Integration Test

ACD Early Integration Test - ACD Early Integration Test - OverviewOverview

Test Description– With 8 Towers in the grid and the ACD installed execute

functional, performance, and internal interface testing of the ACD, Trigger, Dataflow, and Tracker subsystems.

– Perform the LAT CPT, augmented to include the ACD, and SVAC testing while the entire configuration is powered.

Entrance criteria– Complete the planned 8 Tower testing of the CAL and

TRK prior to installation of the ACD– Successfully completion of the ACD Pre-Installation

Test



ACD Early Integration Test - ACD Early Integration Test - PurposePurpose

Reduce the risk of the ACD Integration to the LAT. Specifically, perform the following activities with 8

Towers and the ACD integrated: – Verify and characterize the function and performance

of the Trigger subsystem with respect to the ACD– Verify and characterize the function and performance

of the Dataflow subsystem with respect to the ACD– Verify the ACD performance while integrated to the LAT– Verify CAL and TKR performance is not adversely

effected by the ACD installation– Verify the performance of the LAT as a whole– Validate, to the maximum extent possible, the LAT

Level ACD, Dataflow, and Trigger test scripts and test schemas.



ACD Early Integration Test - ACD Early Integration Test - ConfigurationConfiguration

GSE Configuration– Current configuration, with the following exceptions

• Latest version of LATTE 4.9.x installed• Upgraded BPU installed

LAT Configuration– Eight Towers in the Grid– EM GASU and PDU installed– GASU flight cables installed– ACD and ACD flight cables installed– EMI shield, ground panel, and Bulkhead bracket

installed• Required to mechanically support ACD/GASU flight cables
