Break Out Boxes are ReadyBreak Out Boxes are Ready

• Breakout boxes facilitate interface verification without significant risk to flight hardware. Note that the LAT electronics design does not easily permit measurements of LVDS signaling characteristics at data rate. Four boxes are required:

– 26 pin interface




• Adapter cables adapt between different pin outs, connector styles and sizes. Examples of breakout boxes are shown in the following picture:

EGSE TEST REQUIREMENTS: MD-00408EGSE TEST REQUIREMENTS: MD-00408

• Configuration of EGSE shall be controlled via released documentation

• EGSE shall be acceptance tested• EGSE shall be validated before use if it has been moved,

reconfigured, or repaired– Validation shows that equipment is both ready for use and safe to

use• High degree of confidence that equipment in that configuration

has full operating capabilities– NASA guidance

• Perform an EICIT and an SVT to ensure electrical safety• Trip points on circuit breakers, current limits in power supplies,

shall be verified• While everything is validated, the scope of validation is tailored

for each piece equipment type



STATUS OF EGSE– COTSSTATUS OF EGSE– COTS

• Digital Multimeters (I&T responsible for these)– Calibrated Instrument– Validation Tests

• Embedded within test procedure that calls them– STATUS: Meter purchased exceed maximum voltage for parts in

some equipment, so we are re-procuring• Borrowing “Safe” DMM’s in the meantime

• Hand Tools– Procured, cleaned, and placed in toolbox within cleanroom

• Automated Test Equipment for Safe to Mate– All parts received - calibrated– Interconnection harness designed –in assembly– Rack tray’s sent out for machining – affected by safety stand
