AN/UPM-155 Radar Test Set NSN: 6625-01-307-0512 The AN/UPM-155 is accurate, reliable, and easy-to-use. It will contribute to your organization�s bottom line by providing rapid, cost-efficient turn- around of IFF equipment while minimizing operator training requirements and skill levels. GENERAL DESCRIPTION FEATURES � Built-In-Test which provides both fault detection and fault The AN/UPM-155 Radar Test Set is being fielded as the U.S. DoD isolation to LRU level tri-service standard for IFF test equipment for the 1990�s and � Fully automatic transponder and interrogator test modes beyond. As the AN/UPM-155 entered initial production in 1992, a new world standard in IFF test equipment has emerged. A general � Analog Controller Multiplexers are developed which enable purpose test set, capable of testing all MK X and MK XII compatible complete autotest of the following IFF equipment: APX-64 APX-76 APX-101 UPX-27 KY-533 IFF equipment, including transponders, interrogators and other APX-72 APX-100 UPX-23 KY-532 associated system components, the AN/UPM-155 is designed and � Additional analog controller multiplexers can be developed to manufactured to meet full military specifications. address particular IFF autotesting requirements � Local operator control or remote control through either a The AN/UPM-155 is microprocessor controlled, and features an standard IEEE-488 or EIA RS-232C Interface interactive, menu driven user interface with onscreen help, a high resolution plasma display and an oscilloscope. An easy-to-use � High resolution display permits extensive operator instruction via menus and prompts keyboard allows the operator to interface directly with the AN/ UPM-155, which is completely self testing upon power up. � Advanced measurement capability provides precise digital readout of RF power, frequency, pulse spacing, pulse widths and VSWR The AN/UPM-155 is readily expandable to accommodate emerging � Mode 4 testing can be accomplished using KIT/KIR equipment technologies such as Mode S and secure waveforms. Its open (secure area required) or by using the UPM-155�s integral architecture allows for efficient hardware and software simulator, which generates Mode 4 maintenance codes expandability. � Operator-controlled, multi-function signal generator eliminates need for external pulse generators Menu-driven automatic testing is available through the use of � Modular construction with common CPU bus interface to each UUT-specific analog controller multiplexers (i.e., smart interface functional analog/digital and applicable RF module cables), which adapt the AN/UPM-155 to many common IFF � Designed for future growth with 20% of volume reserved for components. hardware growth and 100% CPU memory reserve.
