90.UNIT UNDER TEST REQUIREMENTS AND DESCRIPTION. Data tables beginning with

“U” in the first positon of the table code are structured to identify the UUT and those hardware and software elements required to test the UUT with offline support/test equipment, The unique combination of these elements required for a specific UUT and support/test equipment configuration is a Test Program Set (TPS). In addition to defining the TPS elements, this information provides the configuration identification of the UUT (i.e., the UUT and the support/test equipment to be used in the test) . This information is

established for each UUT which has a requirement to be tested by the support/test equipment documented. Additionally, Calibration and Measurement

Requirement Summary (CMRS) information is captured in these tables. Figure 9 depicts the relational hierarchy of these tables/entities.

90.1 Table UA, Article Requiring Support/Unit Under Test. This table identifies the UUT which is a component of weapon system breakdown structure. A UUT can be either a component of the system/equipment or a piece of complex SE itself which must be documented under the end article (weapon system) for contractual or provisioning purposes. Table keys are migrated from table XB, but are given the role name “UUT” to distinguish them (UUTLCNUA, UUTALCUA, and UUTLCNTUA). The EIAC must be the same as in table XB, therefore it, is not role named.

NOTE: The keys (EIACODXA, UUTLCNUA, UUTALCUA, and UTLCNTUA) must have a matching set of identical values already established in table CA (Task Requirement) .

90.2 Table UB. Unit Under Test Support Equipment. This table serves as the tie-in between the SE and the WT. Keys are migrated into table UB from the EA and UA tables. Table keys are EIAC (EIACODXA), WT LCN (WTLCNUA), WT

90.3 Table UC, Operational Test Program. This table allows documenting identification and cost data pertaining to the Operational Test Program (OTP). The OTP is used in conjunction with another support equipment item, normally ATE. This table provides supporting information to the UD table. Keys are migrated from the HA table and given the role name “OTP” to distinguish them (OTPCAGUC and OTPREFUC).

MIL-STD-1388-2B

a reference to that element. Table keys are migrated from table UA and include EIAC (EIACODXA), UUT LCN (UUTLCNUA), UUT ALC (UUTALCUA), and UUT LCN Type (UTLCNTUA). Also, Text Sequencing Code (TEXSEQUF) is a key attribute.

90.7 Table UG, Unit Under Test Parameter Group. This table allows documenting specific information about individual parameters which the unit under test requires to have measured, generated, etc. by the support equipment. This table is used when the WT is a subelement of the system/equipment (CMRS category I item), as opposed to being another piece of support equipment, with one exception. This table can be used to document parameters for a piece of complex SE which is an LSA candidate, thereby, making it the WT. Table keys are EIAC (EIACODXA), WT LCN (WTLCNUA), WT ALC (WTALCUA), WT LCN Type (UTLCNTUA), SE Reference Number (SEREFNEA), and SE CAGE Code (SECAGEEA).

NOTE: The WT Parameter Grouping Code (WTPGCUG) and the SE Parameter Grouping Code (PARPGCEC) (table EC) provide the common link between the parameters that need to be tested by the WT and the parameters that the piece of SE can test. Therefore, the values for WTPGCUG and PARPGCEC must be identical to link the WT to the corresponding piece of SE.

APPENDIX A

90.12 Table UL. Unit Under Test Support Equipment Automatic Test Equipment This table cross-references the ATE Test Station (table UK) data with the UUT SE (table UB). Table keys are ATE Reference Number (ATEREFUK) and ATE CAGE Code (ATECAGUK) migrated from table UK and the keys migrated from table UB

which are EIAC (EIACODXA), UUT LCN (WTLCNUA), WT ALC (WTALCUA), WT LCN Type (UTLCNTUA), SE Reference Number (SEREFNEA), and SE CAGE Code (SECAGEEA).

90.13 Table UM. Support Equipment Item Unit Under Test. This table identifies pieces of SE (Calibration and Measurement Requirement Summary (CMRS) category 11 items) that are linked with CMRS category III items (SE in support of the category 11 SE). Normally, Tables UM and UN are only used if a CMRS (LSA-076) is required on contract. Table keys are migrated down from the EA table (Support Equipment) and given a role name of Support Equipment Unit Under Test to distinguish them (SUTCAGUM and SUTREFUM).

90.14 Table UN. Support Equipment Unit Under Test Parameter Group. This table allows documenting specific information about individual parameters which a piece of support equipment (SE) (CMRS category 11) requires to have calibrated, measured, etc. by another piece of SE (CMRS category III item). Data from this table will be used on the CMRS report (LSA-076). Table keys include the SE WT Parameter Group Code (SEUPGCUN), keys migrated from table EA and given role names of “Testing” (TGSCAGUN and TGSREFUN), and keys from table UM are also migrated into this table (SUTREFUM and SUTCAGUM).

NOTE: The SE WT Parameter Grouping Code (SEUPGCUN) and the SE Parameter Grouping Code (PARPGCEC) (table EC) provide the common link between the parameters that need to be tested on the CMRS category 11 item and parameters that the piece of SE (CMRS category 111) can test, respectively. Therefore,
