VXI LVDT simulation COTS resource augments legacy commercial airline industry ATE
M.W. Johnson, David Dayton · 2002
This paper describes Rockwell Collins airline industry automatic test equipment (ATE) and North Atlantic Instruments (NAI) VXI commercial-off-the-shelf (COTS) tester cards. The Collins ATE is used for testing seller furnished equipment (SFE) and buyer furnished equipment (BFE) in accordance with industry standard ARINC 608A requirements. The NAI VXI synchro/resolver card is a module of both the SFE and the BFE ATE. The NAI VXI LVDT simulator card and VXI phase-angle voltmeter are used on SFE. The Collins ITS-701 general-purpose digital emphasis tester is used to test SFE such as the automatic flight director system, maintenance access terminal and standby instruments. Its RFT-1000 general purpose RF emphasis tester is used to test BFE such as the RF sensors, HF transceiver and SATCOM units. Recently, a VXI linear variable differential transducer (LVDT) COTS resource was added to accommodate testing of the 737-next generation autopilot. NAI's model B5410C-83 is an 8-channel LVDT simulator. NAI's model 5390 is a precision synchro/resolver simulation and angle position measurement VXI COTS tester card. NAI's model 227 is a high accuracy phase angle voltmeter.
