LAT EMI TESTING:
BUILDING BLOCKS
THE QUESTION
• What is the lowest equipment level that
can be tested and produce meaningful
data?
ELECTRONICS (1 of 2)
• RE/RS/CE/CS/CM
SIU
PDU
EPU
GASU

PLANS FOR LAT EQUIPMENT
• Review the proposed set of tests
(RE/RS/…) for each piece of equipment or
groups of equipment as depicted on slides
3 thru 7 (Are the proposals reasonable?)
• Next review the proposed test
setup/configuration for each piece of
equipment or groups of equipment as
depicted on slides 3 thru 7
TEST PREPARATION
• Prepare a test plan/procedure for each
piece of equipment or groups of
equipment as depicted on slides 3 thru 7
• The test plan/procedure must be reviewed
and approved by the LAT Project Office
prior to the commencement of any testing
TEST PREPARATION (cont’d)
• All necessary precautions will be taken for
the safe handling and operation of space
flight equipment
• CS06 - Survive testing is restricted to nonflight hardware as called out in 5.4 [4] of
the 0005 document
THE NEXT LEVEL
• What is the next level of testing that can
be done and provides meaningful data and
risk mitigation?
• For example, assume the Tracker test
from chart 6 is one tower, then would the
follow on test be two towers? Is any other
combination of towers useful other than
16? etc.
