Abstract

The LSST Camera focal plane will be constructed with 21 144-Mpixel modules (“Raft Tower Module”, RTM). An extensive operational test is performed to confirm the integrity of all connections and to verify the basic functionality. Each RTM undergoes at least four connectivity tests. A python script communicates with Java- based control software and performs the test. A final script parses the test data and generates a PDF report. The report includes a summary PASS/FAIL table, several hundred current, voltage and temperature parameters, and images taken with the CCD array at room temperature.
