Design and application of portable test system of aero electronic equipment

Currently bus communication technology used extensively in airborne equipment, so most of the test equipment is based on a variety of bus, but in addition to ICD file, the same form of these equipment have the same form. So we designed a portable test system of aero electronic equipment. The system has a simple hardware structure and software design using separate form. The system meets the test requirements of different devices by editing ICD files on different devices. In addition, the system also can measure analog signals and complete discrete I/O control. After a trial in army showed that the system reached the requirements of the test specification and reduced the military´s investment in testing equipment to a certain extent.
