1. IST Chopper Day at Astrium (2007-11-13)

According to Sect. 11 of the PACS IST Procedure Document (PACS-ME-TP-021, Issue 2.5), we will verify the functionality of the PACS chopper during an especially dedicated "Chopper Day" during FM-IST at Astrium. This includes three steps for both the nominal and redundant operations. The CUS scripts are the same for both parts; we will adjust the suitable chopper control parameters by editing and uploading the referring CALU table.

1.1. Chopper Zero-Point Offset Nulling

1.2. Verify Stability of the Chopper

The command sequence is:

  1. WriteOBSID_ast_OBS
  2. CONF_chopper_ast_OBS_Shell

  3. PACS_Chopper_EnDis_Test_ast1_OBS_Shell

  4. CONF_chopper_ast_OBS_Shell

  5. PACS_Chopper_EnDis_Test_ast300_OBS_Shell

  6. CONF_chopper_ast_OBS_Shell

  7. PACS_Chopper_EnDis_PlateauTest_ast_OBS_Shell
