Avionics Test Studio is a package of software-defined instruments running on the Aeroflex 3000 Series PXI cards that aoffers both avionics signal generation and signal analysis functionality. The generator provides all of the standard avionics signals offered by various other Aeroflex avionics signal sources including the (Marconi) 2030 (with Option 6), the (IFR) NAV-750C, and the (JcAIR) NAV-2000R (including emulation of the Collins 479S-6A GPIB command set used in many military ATE systems). The generator also adds several new capabilities that are not offered or as conveniently available on other Aeroflex instruments. Other protocols are planned for addition to the system based on market needs. In addition to the graphical user interface, Avionics Test Studio software includes DLL versions that can be used in any standard ATE system.
