AN/APM-424(V)3 Interrogator/Transponder Test Set The AN/APM-424(V)3 Interrogator/Transponder Test Set is a performance and capability upgrade to the popular APM-424(V)2 "Star Wars" Test Set. With the same point-and-shoot, easy-to-use operation, Aeroflex/JcAIR Test Systems has redesigned the electronics inside the APM-424 to provide Interrogator as well as Transponder testing capability. Mode S test capability with included growth to Mode 5 has also been added. The AN/APM-424(V)3 is a small hand-held unit that consists of an integrated mono-pulse antenna, electronics package and display unit. The rugged antenna employs dual end-fire planar array elements mounted on the upper surface. The electronics package contains a transmitter, a two-channel digital receiver, microprocessor and FPGA-based processing and control circuitry, power regulators and rechargeable battery stick. The display unit consists of an LED alphanumeric display and an optical sight. The AN/APM-424(V)3 easily accommodates a variety of aircraft, ground and ship platforms to test Transponder and Interrogator performance. The unit automatically adjusts both transmitter power and receiver sensitivity to the test environment. This permits the operator to assume a convenient location from 5 to over 250 feet for transponder testing and 50 feet to ¼ mile for interrogator testing.
