Test 001: "1553 Interface Test"
This test shall first verify the electrical characteristics of the LAT 1553 interface, then demonstrate (in conjunction with a spacecraft simulator) that the LAT can exist on the bus without responding to messages directed to other remote terminals. Next, processing of telemetry requests shall be demonstrated, followed by exercising the command interface to the LAT and verifying that all commands and command data are correctly interpreted. Commands need not be executed to successfully carry out this test. Timing measurements for the standard message traffic shall also be performed.
